You may recall the setup I had going a couple of years ago for a client in 
India, where we were landing traffic here in the US and then going out to 
the net routed from several physical locations. The VNC latency was a killer 
(there was a single bad router hop in the UK between us which bombed on a 
regular basis, like a black hole).

We ultimately went with OpenNX:

which worked like a charm. Very low latency and low bandwidth, and worked 
consistently well, even over flaky connections.
