While it may be faster for users over dialup, it does not
do all that vnc does. Across a lan, it's a wash.
There are several other issues, the main ones being:
1 - licensing, you have to have the right combination of windows
products to be legal. ( or even to function )
2 - Multi-platform, vnc isn't restricted to 2 platforms ( for
the 'server' side as TS is. VNC works for most any major
OS, in any combination.
( oh and the http applet is cool if you don't want to carry
around a client disk with you all the time )
