Can someone give me a quick overview on how to use PBuffers? Is there an OpenGL equivalent, or is this purley a LWJGL invention? Are there likely to be older video cards that don't support this feature?

It's a OpenGL feature. Basicly, Pbuffers is the ability to create an offscreen frame buffer and bind the OpenGL context to it, effectively routing all rendering to the offscreen buffer.
Pbuffers is an extension (can't remember the win32 name. GLX 1.3 is required on linux), and can't be guaranteed available. Also, we haven't implemented Pbuffers at all on mac. It seems they're only available from 10.3 onwards.

For now it may actually be easier just to use the backbuffer for your sinister purposes before you start actually rendering the scene itself.
