Hmmm... that's a good one. The citrix client software creates a cache for 
machines on slow links (although on 486's it often better to live without it - go 
figure).

How difficult would it be to output the screen updates to a machine's temp file 
location. You could always bin them on exiting VNC (or keep them all if you had 
a switch). Hell, could you make a temp file based on IP address, machine or 
DNS name...... would that speed up VNC on slower links?

Later,
Richard
