While this is
an interesting write-up, I’m deeply skeptical about this procedure making any practical sense.
There are a lot of things I'm finding the iPad appealing for, but this is not one of them.
Now, what I think would be really interesting is if my DSLR and my iPad could establish an ad hoc wireless network and my camera could pump “tethered” JPEG proxy images to the iPad for immediate review and forwarding on to internet services like flickr.
