I recently upgraded my wife's desktop at home to WinXP Pro SP2, and Terminal Services still doesn't seem to support multiple concurrent sessions - if she's logged in and I try to log-in via TSC, a pop-up window on my Axim X5 warns that it'll log her off in order for me to log in remotely.
Oh well, maybe someday M$ will get it right.... Sure!
I do agree that TSC is a LOT faster than VNC, but you do give up image quality (only 8 bit with TSC) to get that speed. Unless you already use a VGA PPC, with QVGA you're already giving up a lot on image quality, so I think the tradeoff is well worthwhile.
Anyway, this VNC/TSC stuff is quite interesting, but obviously we're still pretty darned far from the holy grail of browsing capability via our handhelds (c'mon already, Minimo and/or Opera!). At least with VNC/TSC, I can excecute Javascript commands that my webmail account requires for full functionality (even NetFront doesn't work completely!).
