@Shadeetree – usually a RAW file approximately weighs about 28MB. I wonder how the transfer rate would actually be. Most DSLRs get stuck for seconds while saving the RAW file to SD if the SD card does not support high speed R/W. I wonder how Eye fi card transfer the image while capturing another one.
The Mobi is intended for more casual users, the ProX2 can upload RAW files, is able to transfer to any folder location on a local computer using a PC based software utility to constantly monitor for the EyeFi.
Oh no, I would never suggest keeping the card away from any authority! In fact, I would suggest that this is the card you do want to give them. As for range, I'm sure it's short, but it would be best to know by how much. Different cameras will have different ranges depending on how much the card is shrouded by the camera body. My LX5 has an all metal body including the door covering the memory card. I would begin a range test with a card reader that puts the EyeFi card out in the open air, just to get a theoritical maximum. The card reader would also be the best way to tap into the power supply to the card so as to measure how much current is drawn while in standby and while in file uploading.
