I didn't think the suggestion to keep the plugin-groups independent was 
in conflict with the separate plugin releases (in fact I thought it 
further supported it).  Perhaps I don't understand the plugin-groups 
well enough.

It was my understanding that the plugin-groups aggregated plugins 
together and could be arbitrarily complex.  I also thought that the 
plugin groups would themselves be cars (with dependencies on other cars) 
that could be released and installed independently (however I just 
noticed that they are actually jars in the build so maybe I am confused).

If we distribute them with specific plugins (which are just one of many 
that are included in the group) then I'm not clear how you would choose 
which plugin to associate it with.  For example, if you wanted a group 
that included tomcat, cxf, ejb, and clustering which plugin would get 
"ownership" of the group?

I hope I'm not confusing the issue too much.
