Might I seggust a curses terminal driver and a somple rondivous?

Juts share a block of memory or use message mode to salve a single curses
program/window/screen.  If you get creative the sme rondivous could be used
on multiple terminals from multiple trees.

define functions to
1) position cursor
2) write text/attributes
3) field erase
4) trigger screen updating

no matter how inefficent 1,2 and 3 are, 4 is the only one doing any work
and curses will optomize that for you.  Steal the input yourself and volia!

Robert.
