Strange - our experience is that NX is quite robust - enduring up to
about 7% packet loss usably (although anything over 2-3% has a
noticeably impact) and working quite nicely with latencies up to 100ms
or more. It seems orders of magnitude faster than VNC. In fact, it is
the fastest and most responsive WAN solution we have seen although RDP7
has significantly closed the gap - John
