Sony Multi-TouchScreen can do up to 5 Contacts

Iphone sets the tone for multi touch sensation; even Sony wants to play with multi-touch technology. The Japanese Giant has developed one of their own with optical sensing technology that allows up to 5 points of contact on the polysilicon film display. The protocol is said to have VGA resolution of 640x480 and will make its way to mobile devices, media players, consoles and other portable devices. If we aren't too lazy and spoiled with remote control, a bare multi-touch big screen TV is not a dream. But I think they have to make flying couch first.
