It's probably a really difficult job to program it.

I'll tell you -- every time I say something to nearly anyone about VNC, if
they've heard of it, but aren't expert on it, the first thing they say is,
"VNC is not secure."  Having a version with encryption built in would
definitely make VNC much more appealing to a lot of people.

I can agree that it is even better for Windows, but I think it makes
plenty of sense for Linux.  Without it, if I'm at a computer lab and want
to connect to my server, what do I have to do?  You know the steps.  It's
a few minutes of work, and that is assuming the machine will allow me to
install PuTTY (or whatever).

Yes.  We need that, don't we?  It must be really difficult to program such
a thing or we'd have it already.
