I've created a wiki page from which we can link to 3rd party modules.
http://code.google.com/p/google-guice/wiki/3rdPartyModulesWe or other programmers can create separate projects (using Google Code Hosting or whatever you like) which build on Guice. Off the top of my head, you could implement the EJB 3 interceptor support and "bean autowiring" externally. These 3rd party modules can release independently of the core Guice. We could also move the Struts 2 plugin out if we like.
Once we have enough modules linked, I'll feature this wiki page on the Guice home page.
Thanks,
Bob
