I sometimes run VNC over the local network in my home, so I have a
pretty good feel for its speed on ethernet. Admittedly, X11 might be
able to work a bit better, being window/widget oriented rather than
whole screen. But VNC is pretty smart about recognizing pixel diffs and
using compression... more so than X11.

Anyway, it's usable enough, but definitely not as crisply responsive as
a local screen. The EVM GUI isn't that complicated though--no dragging
windows and animated icons--so maybe it's OK. But a few extra
milliseconds here and there can create a bad impression of a system. I
use VNC in a hackerish mode, and know what to expect, and why. Most
voters aren't as savvy; nor as tolerant.

In any case, bottom line is requiring a smart terminal just shifts the
burden, and is basically worthless to us. Whatever our CPU looks like
in physical dimensions, it needs a video output port.

Yours, David...
