Anyone tethering a Canon 5Dmk2 to an iPad??

I'm thinking about getting a new iPad and tethering it wirelessly to my Canon 5Dmk2. I know some people have done this with Eye-Fi SD cards, but my camera takes compact flash cards only.

I'm looking for something reliable, cost effective, and easy to use. I also want it to be reasonably fast, so it doesn't slow down a studio photo session. As I understand it, it's best to shoot RAW + small jpg, then send only the jpg to the iPad. Whatever card I buy has to be able to upload to LightRoom 4 via a card reader.

Any good suggestions that are fairly current? Thanks for your help.
