OSGi platforms (Equinox) should be a good platform for dealing with
software
updates. Some service could look for updates (automaticaly/"manualy"
triggered),
download them and then replace the outdated bundle.
My question is: How "deep" can the software update work? Are their
possibilites
that the software update service can also update itself or the complete
platform
without restarting the JVM?

the update can go pretty deep. The Eclipse Update Manager for example
allows you to lay down new versions of any bundle (including the framework
itself). In some cases the updates could be activated dynamicially (without
restarting). However, in general, the bundle being updated needs to be
first stopped, then updated, the restarted. When you update the bundle, any
bundles that depend on it must also be stopped and started.
So you see that, for exapml,e updating the runtime bundle would likely shut
down all/most of Eclipse. Note also that it requires all the bundles
involved to be clean (unregister listeners etc).
You can also update the so-called "root files" (eclipse.exe, config.ini,
startup.jar) if you use install handlers.

Sounds pretty good. But how does the magic work that code which is
currently running (update service?) replaces itself (file locks,..)?

Updating bundles is ok since you are actually laying down a completetly new
JAR beside the old one. Then you either restart the framework or recycle
the bundle.
Updating the root files is more complicated. Right now updating things like
eclipse.exe and startup.jar is harder because they are shared and typically
locked and do not have version numbers. We have been talking about a)
making stratup.jar into a versioned file (perhaps in the plugins dir) and b)
a way of updating eclipse.exe by putting a copy beside the old one and then
swapping on restart.
