That last part is true, once you vote on something, you cannot change it anymore, and voting
on 1.0RC and then 1.0 (with the version number being the only change) sounds like a waste.

There are no rules for versioning, but I would keep things simple. Vote for "1.0" or whatever
version number you as a community feel is appropriate. The worst thing that can happen is
that it fails, in which case you bump the version number and try again.

Project wise, Celix probably resembles Felix the most. Here we have a trunk with directories
for each "module". Modules consist of one or more related bundles, and we release modules
individually (or sometimes a few modules together). Every bundle within a module is versioned
individually. That is not a problem for a release (having different versions in one release).

In ACE we do it differently. ACE is an application, built out of OSGi components, and we decided
to release it as a whole, so all bundles at once.

Remember, in the end, Apache is all about doing *source* releases. That's also what you vote
on. All binary releases are for convenience only (you see many projects vote on source + binary
artifacts in one go).

With my "personal hat" on, I would say: keep it simple, just release everything everytime
for now and start worrying about separating the code into modules later. For now it probably
creates a lot of extra work, voting for all the parts.
