Hey Christian,

We should talk about your project since I am deep in the XACML/SAML P*P
world these days, trying to help the OGC figure out what GeoXACML really
means to them in the context of OGC web services, and looking at lots of
different implementations. 


Apache 2.0 is incompatible with the GPL v2.0. Indeed, a major motivation
of GPLv3.0 was to allow the integration of Apache and GNU code. GPLv3 is
compatible with Apache 2.0. Unfortunately, I don't remember any of the
details so I don't know how this affects the LGPL v2.0.

If this could be a blocker for you, I'm sure the PMC could be persuaded
to change the license back to include the ", or at your option, any
later version" clause that would let you keep working. No one
particularly cared if I remember right; the choice resulted partly
because I had harmonized a bunch of code before I hit a header that used
the 'or any later version' language so it was easier to kick it out that
to keep it in.

So it sounds like it could be a good project of GSOC.
