Because while X is good^Wvagely acceptable at remotey viewing a set of single 
windows over a medium bandwidth connection, it's horrifically bad dealing with 
entire desktops, especially over low-medium bandwidth connections?

(tightvnc is usable with the desktop being viewed on a 56k modem, albiet not
in the best quality, which is hideously useful for fixing other people's 
computers.  X is clearly not, tho admittedly some of the x protocol 
compression packages do make this somewhat possible, it's still not great).

I cannot even begin to explain how much of a horrifically bad solution
to the problem this is.  Replacing VNC with X is just as bad as replacing X 
with VNC.  See "right tool for the job".

Maybe you'd like to fix it - although I disagree with your assertion that 
it's useful for real world applications, it'd be a useful testbed
sometimes:).
