vnc+vic=better relay?

[Michael Grobe]

rdo, et al.:

i think vnc is a great AG tool, especially when coupled with the 
unix-based VNC relay, but it works with unicast and so generates 
beau coup net traffic....so i was thinking it would be nice to 
modify it to use multicast... at least when running in listen-only mode.....

but then...in an unguarded moment...i thought...why not run a VNC client
on a unix box and use the X11 "device" in vic to muliticast the VNC
screen to the world....(this would be especially nice if the "raw"
codec were used, but perhaps that's not necessary).

the only problem with this is that the X11 device shows only that
portion of the screen within 0,0 and 100,100 pixels (or so)...
and even though the menu offers to change this region, it does not.

i'm wondering if this region can be changed by some X magic i don't
understand, or, if not, whether the source can be hacked to enlarge
the area to something more useful...say 1240x800 or so....

anybody (like you, bob) have an answer?
