Is there a gadget like this?

[Boghog]

I'm looking for a gadget that will wirelessly transfer my screen content to any video projector (usually with a vga-port). The smaller the better.
Ideally it would work via some kind of automatic screen sharing through wifi or bluetooth. Or it might be a two part system that requires me to plug something into the video-out of my computer. I just want to do keynote presentations without the wires.
Does anyone know of such a gadget?

The trouble with this is the bandwidth for it. Bluetooth isn't fast enough. A google search brought up this thing, which might do the trick, assuming the distance and resolution are high enough:

It also runs about $300, and no word on Mac support. If you want to cough up a lot more money, you could look into some sort of wireless HDMI device, but then you will be up into the $1k range, and I'm not sure some of these devices are on sale yet:

Thanks a lot.

Infocus made some too, but I'm not sure they work with Macs, and their description of them is very confusing. Also after years on the market, I've still never seen anyone use one.
