You know, if you wouldn't have made such a nice tool we wouldn't be bugging you so much
for new features :-)

I was just trying to think outside the box with the ssh thing.  I really hope that in
the future many people will be clustering servers.  That will really help things catch
on in larger schools and districts.

Good luck with the vncsnapshot feature.  That will a handy feature.  I use it all the
time with Mac clients and Apple Remote Desktop.  Sure makes it easy to keep an eye on a
room full of kids.
