No Skype video on the NIT.

For a video call from NIT to PC you have the following:

1) SIP based using h.263/h.263+ video (PC clients like Eyebeam, linphone, etc)
2) Gizmo Project with PC 4.0 beta software
3) aMSN on the tablet to MSN Messenger on PC

GTalk or Jabber/XMPP to PC would be an option also, *if* there were any PC software that supported jingle-video. It amazes me that there still isn't any out yet.
