Have you tried the Canon EOS Remote App? (http://www.usa.canon.com/cusa/consum...isplay/EOS_app) It should connect with your iPad. The only problem is that it converts RAW to S2 JPEG size, but that could be just to an iPhone. Another option would be an external hard drive with WiFi, that might work also. Providing you use a PC and not a Mac, a third (and possibly expensive option), is to get the Microsoft Surface Pro when it comes out. It will have a full version of Windows 8, a full sized USB 3.0 port and it will run any desktop application you can run on a Windows 7 or 8 machine.

Hope this helps.
