You know, I think that commuter series might work. Here's my idea. I got the inspiration from the work some are doing with the Palm inductive charging system. Hopefully, I'll be able to take a case like the Commuter series, cut a hole in the silicone right there over the pogo contacts, possibly dremel a little bit of the hard shell away too if needed, maybe even cut a hole there? ?? Then epoxy the following into the case and use conductive tape to trace a path to the inside on the back and put the inductive charging circuitry there. There you would have an inductive charging case without taking up any usb port or anything.
Here's the pogo pins:
Digi-Key - ED8110-03-ND (Manufacturer - 811-22-003-30-000101)
They are 3.48mm tall uncompressed and 2.49 mm tall fully compressed, so you're looking at 0.1" thick. I'm not sure how thick the Commuter case is on the side, but I would think I should be able to make something work with that? Any ideas?
