This sounds like some very impressive work.

If you plan to provide new X extensions, I highly suggest that you do so by
making use of XCB.  Describing your extensions with the XML-XCB protocol
description format will give you an automatically generated client side
library, and soon some of your server-side code.  Furthermore, XCB's latency
hiding and other optimizations should specifically help extensions like yours.
Feel free to subscribe to the XCB mailing list xcb at lists.freedesktop.org and
ask us for any help or information you might need.

Good luck on your project!
