does equinox know about these locations, and can we install a bundle to a

However, I'm not sure that this really is your question. What mechanism are
you using to install the bundle? Update manager? other? Or, when you stay
"install a bundle" do you mean call BundleContext.installBundle()?

We would separate the base plugins and the dynamic plugins into several
extension/install locations.
the update manager, as far as i know it, does only provide full download and
pre-installation of a complete feature. the feature and extension point
shema is designed to load lazy from file, but not load lazy from server. ?
we do not know and we did not find any documentation about how the update
manager handles multiple install and extension locations.

Thanks for the clarification. You can think of features as just lists of
pluigns to install. If there happens to be only one pluign in the feature,
that is ok too. So you can wrap your individual bundles each in their own
feature and put them on an update site.
Sidenote: you do not have to list all available features in the update site
site.xml file. This file needs only to list the features you want users to
be able to see i the update UI.
Then you write some code that identifies and acquires, on demand, the
features that you want for the various dialogs etc.
As for multiple locations, I'm not sure. When you install a feature I
believe you can say where it should go. Eclipse itself (the runtime)
doesn't care where it goes as long as Update tells it.

bundles to in respect to different extension-installation locations ??
b.) who does scan the different install locations for available pluigin and
installs them on startup ?
c.) if we give BundleContext.install a remote url -> is the bundle copied to
the local disk into any install-location (directory) or simply downloaded
and cached in memory ?
more general questions:
..) where can we find more additional documentation (books) about such update
manager and equinox details ?
..) what is the direction of feature and update-manager development. what
kind of additional flexibility in respect to dynamic remote download and
installation will come ?
thanks

the extension locations etc are in fact Update notions. Update tells OSGi
where the bundles are after downloading and storing them where Update thinks
(or is told) they should be. This is the url given to installBundle()

It could be anyone (i.e, it is not a special operation). In the typical
case the org.eclipse.update.configurator plugin scans, discovers, and calls
installBundle.

Unless you use reference: URLs the framework always copies the bundle
content into a disk cache in the configuration area. If you use a
reference: url (as we always do), the bundles are expected to be in the
filesystem and are left in place. that is, they are just referenced.

There is some information in the RCP book (http://eclipsercp.org). Perhaps
the Java Developers Guide to Eclipse
( http://www.awprofessional.com/bookstore/product.asp?isbn=032 1305027&rl=1)
has some info as well.

Eclipse 3.2 includes some improvements in performance and robustness and a
few new features but it is largely the same design/mechanism as before.
Looking further down the road we are currently thinking about the
requirements. Various people have been enterning bugs and enhancement
requests with usecases, scenarios and proposed behaviour. We'll be looking
at that after 3.2 quiets down.
