[xwiki-users] LGPL w/r/t plugins - are they derivative?

[Catalin Hritcu]

Found one more relevant link:
http://www.jboss.com/opensource/lgpl/faq#bundle

So in an better world (that uses components, and well defined
interfaces) it is possible to have non-LGPL plugins to LGPL code.
Probably this will be the case with XWiki 2.0. This does not mean that
now it's not possible, just that it's might not so easy technically
and legally to do so.

Once again, just my 50 cents.
