I'm not sure its an issue.=20
Each bundle provider should have its own policy.=20
The  first one is more independant of oscar evolution (version
modification), whereas the third relies on current releases, and should
fail to compile on different oscar releases.

One issue I can't see is the sources packaging model...
- jar/tar/zip ? (jar is cool but generates META-INF directory with jar
  tool, or you use your inner unjarrer)
Do you rely on a standard build.xml skeleton ?
(clean/compile/bundles)

Do you extract sources inside oscar install ?
So you need some kinds of bundle/package/services namespaces.
Initial namespaces were provided by both osgi and you, but what will
appened when billion of bundles will be available :) ?

Il like the gentoo portage tree (or freebsd port) which should be
reproduced.
