I was once excited about creating a plugin system for AppFuse, but now I'm not sure it's a good idea. I've used a lot of plugins in Rails and Grails and they always seem to be abandoned or not compatible with the latest releases. It's great to have an ecosystem around a project, but not if they're not maintained. Witness what happened with Eclipse a few years ago - they had to establish a "release train" every June and start developing many of their core J2EE plugins in-house instead of relying on 3rd party developers. I don't know if it's a good idea to go down that path.
As for OSGi, I used it a couple years ago at LinkedIn. It's a cool technology and promises a lot of great things with hot-swapping and such. However, I get the feeling if you're developing an OSGi-based system early on in a project's lifecycle, you might be over-engineering. I think the SpringSource Slices thing is very cool as we tried to do something similar with Spring MVC. We got it working, but it wasn't easy. More than anything, if someone wants to put the effort into 1) creating OSGi bundles of AppFuse modules or 2) developing a plugin system - I'd be happy to welcome the contribution. However, it's not something I plan on investing my time in. I think it should be possible to leverage what Spring or Struts 2 has done in this area to get the support you're looking for.
