Would there be much demand for me to continue working on getting the WFT-4a and 5A to FTP files directly to the iPad so they could be seen in the photo app? I have the iPad allowing connections currently and will recognize jpeg files. I am not sure why it isn't liking Canon raw files, but jpegs work. I don't have a 4A or 5A to test with, but it should also allow for an AdHoc network connection so you could use the HTTP connection on the grip with the iPad.
