Okay, let's try this from a different perspective:

Those of you who make presentations at computer programming conferences: You bring your own laptops, don't you? How do you connect to wireless projectors? Do you have to install the hotel's software on your laptops in order to do so? And how does this work in large-room presentations where multiple projectors hitting multiple screens are all displaying your presentation.

Any information I can get on this would be helpful.

The stumbling block, for me, is this: If I connect by wire from a laptop to a projector, I do it with a VGA cable. The existing video driver on the laptop sees the projector as a second monitor. It gives me option to use either the projector, the laptop. or both ("clone") as my monitors. I don't have to install any special software or hook up the projector to the network.

Why is it so difficult to enable this same kind of connection wirelessly? What I think I really need is wireless transceiver dongles that plug into the laptop's and projector's VGA ports. Why should I be forced to go through the rigmarole of a WAP and a "network device" metaphore when all I want is for the projector to be a second monitor on my laptop?
