I'm after a solution to transmit VGA over wireless. I want a receiver sat behind a TV in our meeting room, and a sender that i can just connect to any presenters laptops without the need for drivers or software (this bit is crucial, so the USB ones are no good) a company called Gefan seem to have done them in the past but they don't seem to do them anymore (discontinued) they only seem to do HDMI ones anymore.

Can anyone suggest one? Seems my googlefu is failing me.
