Any contributions are of course highly welcome. Please let me know when 
you have something working here. Would be glad to take a look.

The CVS resources are at the RT repository:

http://dev.eclipse.org/viewcvs/viewvc.cgi/org.eclipse.equinox/weaving/bundles/?root=RT_Project

http://dev.eclipse.org/viewcvs/viewvc.cgi/org.eclipse.equinox/weaving/features/?root=RT_Project

Hope that helps!

Are you planning on implementing just pure aspect weaving for AspectJ, 
or are you also looking at the different aspect resolving mechanisms 
(opt-in vs. opt-out) and the caching for woven classes?

Cheers,
-Martin
