Bad luck for you, Mike.
FBO would be the way to go, it is much more elegant than using pbuffers.
I don't know the current state when using pbuffers and OpenGL performer.
I think there has been some discussion on this list. There are also some
Performer examples in the pguide, but I don't know whether they work or not.
If you want to have an high level abstraction to all this you should have a
look at
http://www.gpgpu.org/developer/
and check out the FBO and rendertotexture utility classes.
And now for sth. completely different: You could also create your own
GLcontext and use it when creating a pf(Pipe)Window. You could create a
window and a GL context within your java app and the use this context when
running performer...
