what about the SD memory cards that have integrated wifi?
Eye-Fi SD cards? I hadn't thought of that. That certainly removes about half of the programming from the equation but that doesn't concern me. I'm just doing a proof of concept. The people I show it to can figure out how they would like to implement it.
EDIT: Wow this is unfortunate but Eye-Fi is not what I'm looking for, and there really isn't anything that competes with it. Eye-Fi's firmware specifically only transfers JPEG files. It's amazing how much potential the product loses due to this intentional limitation. I did read that some people had success with saving data with a jpeg extension if it was over 16KB. I think using this product might be more hassle than it's worth though. Unless someone knows of another similar product that DOES allow unlimited access to any of the files on the sd card over wifi?
