I've been mulling screen capture code. I tried PIL's

pymedia is pretty quick once I hand it the data.
There has to be another way to get a copy or buffer() of the screen
DC's data that is faster (I hope).
Yes, but I doubt you can get faster without writting a specific program.
- watch for invalidate and paint events so you just grab the screen
areas that actually have changed.
- use a "pseudo video card" driver to watch for drawing primitives as
TightVNC does (or is it some other VNC clone?)
