Hmm.  I guess that's reasonable, provided I make sure there isn't one set 
already.  (How to do that in Perl?)

Wez & company -- I don't suppose you want to standardize on some
environment variable that, if set, would be used by vncserver instead of
the default ~/.vnc/?  (Perhaps even have vncserver set it as suggested
above if it doesn't exist at runtime, if you want to make me really
happy.)

True...but people won't, so I'll either have to require anyone who wants 
to run stuff on connect/disconnect to set such a variable, or come up 
with a default.

Wait a second...here's possibly a much better idea that fixes pretty much 
all the problems.  How about I just check for the existence of certain 
variables (VNC_RUN_ON_CONNECT and VNC_RUN_ON_DISCONNECT are unambiguous 
but pretty ugly, anybody have better ideas?) containing full path to a 
command, and if they exist, run them when appropriate.
