Although Tcl/Tk is very useful for creating the interface, it is much more
flexible, because it IS a programming language. I know of two extensions
which will make communucation over TCP easy (tclTCP and tcl-dp). I will 
have to take a closer look at them though. I do not know what exactly 
you want to achieve with the interactive graphics, so I cannot properly
comment. The Canvas widget does get slow with LOTS of objects, but even
then it will still be faster than current practices (like sending a new
bitmap after each command). And alternatives are possible, such as sending
commands wich will modify the bitmap displayed locally.

To achieve the impossible, one must think the absurd.
to look where everyone else has looked, but to see what no one else has seen.
