Automated Wireless File Transfers?

Maskirovka asks: "I'm in the process of designing a helicopter mounted compact flash reader/transmitter package to upload photos to a fileserver upon landing, probably using 802.11g. It needs to be idiot proof (ie, plug a flashcard into it, and it'll upload automatically as soon as it gets in range of the basestation), and should weigh less than 5 pounds so as not to affect the aircraft weight and balance. It could probably be built around a Via EPIA board using a PCI WiFi card and riser, but that almost seems overkill for the one specific task. Is there a more efficient way to do this with off the shelf hardware?"
