Has anybody used their TR to connect to a wireless video/data projector?

I am looking to buy another projector and I am giving some consideration to purchasing a wireless one. Only downside I can see is the 802.11b Wi-Fi, in my TR1 MP, which would mean a really slow frame rate when sending video to the projector. Data and pictures I expect would be ok. Not sure video would be much better at even faster speeds using other cards.

If anybody has tried this, I would be interested to hear their thoughts and what make and model projector they used.
