I hadn't heard of ultravnc before, but I'd guess it's just
a customized version. Right from the RealVNC homepage is "RealVNC is a
UK company founded in 2002 by a team from the world-leading AT&T
Laboratories in Cambridge. The company was established to commercially
develop, enhance and promote VNC, the innovative remote access software
with a widespread international user base."

VNC was originally developed by Olivetti Research Labs (AKA ORL... who
did a lot of other really cool stuff) and a couple years back they were
bought out by AT&T and are now called AT&T Labratories Cambridge
(http://www.uk.research.att.com/). The RealVNC people were are all
former ORL employees who IIRC, left to form their own company sometime
after the buyout.

TightVNC (xtightvnc package on debian) is what I use. It includes some
performance enhancements over the original (it's backwards compatible
though. The extra features are only available if both ends support it).
Their main focus I believe is optimizing the compression, which makes it
easier to use over a lower bandwidth connection (like when I'm fixing a
problem on my parent's Win98 box 3000 miles away over a cable modem
connection).

MS has a different view on things than your standard UNIX user.
Remember, Windows is all about the GUI. Up through Win2K, I don't
believe there's really any way for multiple users to be logged onto the
same computer at a time. I believe with WinXP this may have changed, but
I don't know the details (I haven't even touched a WinXP box yet).
