Then you have two possibilities: 1) Specify ranges in the "Your product" IU - In this case "Your Product" just has ranges on all the things it uses, which then allow you to replace anything by requesting the install. For example you would be able to replace CDT with another version by just picking something from an update site. Note that this solution would not tell the user when there are updates available, but would give power users the possibility to mess around :)
2) Do not use a top level IU - In this case you no longer have the "Your product" IU. Instead what you initially distribute (probably through a zip) would be |--> CDT 5.0.1 |--> Platform 3.7.1 |--> RSE 2.0.0 which allows you to install and remove any component at will (the previous setup you would not be able to get rid of CDT) and also benefit from the notification of new updates.

That makes sense, but it's a bit heavy for what I'm trying to do. The
final mix will be used for internal testing, not for delivering to

with an existing product. I had hoped I could "swap in" a newer build
of the platform with minimal hassle. Having to define a new top-level
product IU, while possible, is a significant inconvenience. It would be
nice if I could tell p2 to relax its dependency checking and just let
me remove and install whatever I want--sort of an
"expert/let-me-shoot-myself-in-the-foot" mode. If the end result is
broken, so be it.

Assuming your product has the following dependency structure
(where each item in the tree is a p2 IU):

CDT 5.0.1

Platform 3.7.1

RSE 2.0.0
|--->
Platform 3.7.1

Platform 3.7.1
then you will have to create a new version of the "Your product"
IU that points at new version of the pieces.
Your product 1.1
|-->
CDT 5.0.2
|--->
Platform 3.7.2
|-->
RSE 2.0.0
|--->
Platform 3.7.2
|-->
Platform 3.7.2
This structure gives you complete control over what your user
gets since when you publish a new update, the user sees that there is
an update to "Your product" and not the individual pieces he does not
want to know about. Note that even though the product version has
changed only the bundles that have actually been changed will be
downloaded.

So, it looks like I'm still
stuck. We now internally have a p2 repo
with the platform.ide IU. So, I can upgrade a pure platform
installation (an installation with only the platform and no upstream
components) via p2 thanks to the help I got from the folks on this list.
However, what I'm ultimately trying to do is upgrade the platform in a
complete Eclipse commercial product--an installation that has not only
the platform, but CDT, RSE and a variety of other components.
Naturally, they all have a dependency on the platform.
So, the question is: how do I swap in a newer platform without
uninstalling all the upstream pieces that rely on the platform? Is that
at all possible? Is there a way to tell p2 "uninstall this piece even
though other things depend on it, so that I may install a newer version
of it".

If I'm reading what you're describing correctly, you are
starting
with a 3.6.0 SDK zip. You can't take a 3.6 SDK and replace the platform
that it contains. What the error message you posted says is that the
SDK 3.6.0 requires the Platform 3.6.0 and if you install Platform 3.6.1
then you will break it.
Coincidentally enough, the p2 team has been working on a new feature so
if you run into the problem described above, we will recommend that you
also update the SDK to 3.6.1 (if available) and then your install will
complete. The feature is almost implemented and will appear in the 3.8
integration builds soon.
If you use the Platform zip (e.g.
eclipse-platform-3.6.1-macosx-cocoa-x86_64.tar.gz) you will see the
platform.ide IU:
<unit id='org.eclipse.platform.ide'
version='3.6.1.M20100909-0800'>
So to fix your problem you either need to use a Platform zip (and
update the org.eclipse.platform.ide IU) or change your command-line to
update the org.eclipse.sdk.ide IU.

There is no IU called org.eclipse.platform.ide in the p2 zip (org.eclipse.platform-3.6.1.zip). The only IUs
in that p2 with 'platform' in the name are:
org.eclipse.platform
org.eclipse.platform.doc.user
org.eclipse.platform.feature.group
org.eclipse.platform.feature.jar
org.eclipse.platform_root
Here's what I get (cleaned up) when I try to
update
the platform in the 3.6 SDK with the one from the 3.6.1 p2 zip
Cannot complete the install because of a
conflicting dependency.
Software being installed: Eclipse Platform
3.6.1.r361_v20100909-9gF78GrkFqw7GrsZnvz0JWNTeb6fue6896L
(org.eclipse.platform.feature.group
3.6.1.r361_v20100909-9gF78GrkFqw7GrsZnvz0JWNTeb6fue6896L)
Software currently installed: Eclipse SDK
3.6.0.I20100608-0911 (org.eclipse.sdk.ide 3.6.0.I20100608-0911)
Only one of the following can be installed at
once:
Eclipse Platform 3.6.0.v201006080911
(org.eclipse.platform 3.6.0.v201006080911)
Eclipse Platform 3.6.1.v201009090800
(org.eclipse.platform 3.6.1.v201009090800)
[snip]
I've tried specifying each of the IUs listed
above.
None of them work.
Finally, here's the cmdline I'm using:
"C:\eclipse_3.7\eclipsec" ^
-application org.eclipse.equinox.p2.director ^
-nosplash ^
-consoleLog ^
-profile SDKProfile ^
-installIU "org.eclipse.platform.feature.group" ^
-repository file:/f:/temp/testp2/plat361p2 ^
-destination f:\temp\testp2\sdk36\eclipse

Yes, you should be able to update the platform
