Glad you asked!

There is API to allow you to specify that textures should be
pageable (requires special formatting in the GL) and you can
specify if a texture should be continuously reloaded.
There is also exposed API to let you force the formatting and/or
loading/reloading of textures.
You can also specify a set of mutually exclusive textures
that should all apply to the same geometry. You can then specify
the mechanism by which those textures should replace each other:
by automatically idling the previous texture and freeing its memory
or the more restrictive method of actually sharing the same texture memory.
You then select the current member of the set to be used.
2.0 also supports texture sources of Sirius vidio and framebuffer.
All of this hangs of the same pfTexture primitive from 1.2 so
Sample programs are provided.

Trying to finish docs and ship this stuff!
