Not possible AFAIK cwbash, sorry. You can transfer the camera raw files through the CCK onto the iPad, but you cannot do anything with them there. It is simply a storage medium / backup device until you get back to a PC. Even then you are usually much faster pulling them back off the camera / card reader to your PC.
I'm a keen amateur photographer myself, but because of the storage limitations on the iPad I don't use it to store my RAW files, even temporarily. Not enough spare storage!
It's great for reviewing JPEGs in the go and great when you are on holiday without your laptop, but it's not (yet) a great device to fully integrate into your photography workflow.
Fingers crossed for the future though! It can only get better...
