Hi,
There is a product available that is an SD memory card with wifi built in.
Its designed for digital cameras, originally for news gathering, where the reporters cameras SD Card would apon entering the publishers wifi network, begin to download its pictures.
So when the reporter logged on his/her pictures would be on their server ready to go.
google wifi sd card
google wifi USB Memory
Gives USB sticks that you can upload to, it might be worthwhile seeing if they also download via Wifi.
