Question : Problem: VNC in a seprate Session on a WinXP box?

After reading the following post: http://www.golod.com/2005/10/enabling-multiple-remote-desktop-sessions-in-windows-xp-professional-and-media-center-edition-2005/
I found that it is possible to use RDP on a "WinXP" or "Win Media Center" box to run multiple sessions (meaning, if someone logs in remotely it won't interfere with the local user).

My question is; Is this possible with VNC?
If so, how, and what version of VNC should I use to accomplish this (i.e. TightVNC, UltraVNC, RealVNC, etc...)?

Answer : Problem: VNC in a seprate Session on a WinXP box?

When uses login through RDP, they get a Terminal session. Meaning each user has thier own independent session.  When users login via VNC, they take control of the actual desktop of the console.  If others are able to login via VNC, they will all be connected to the same session, not independently of each other.  While RDP is more of a virtual session, VNC is an actual "take over" of the desktop.
