I had a quick look and didn't find the threads you're talking about.

Are there widely supported VNC extensions for accelerated graphics ?

I'm not sure what you mean by `focus cycling'. I often develop X GUI
programs in two halves, one of which embeds a window in the other.
This conveniently allows the two halves to be in different languages,
differently versioned, provides additional concurrency without the
need for threads, etc.
Only one of the perhaps many programs in any toplevel should put up
conventional UI elements like menus and buttons.
