pbuffers?

I've looked into the way pbuffers operate a bit and I'm wondering if you considered using only one pbuffer, copying it to a texture and then reusing the single pbuffer. rather than using the pbuffers directly as textures. I know there will be a performance hit, but it shouldn't be too big. This should allow us to use plenty of intermediate textures without running out of space on memory limited cards.
If the performance hit is significant maybe you could use pbuffers for the first 4 dynamic textures, and switch to copying to textures only if more is needed (probably only during scene fades)
this presentation has some info on copying pbuffers to textures
