So one of my problems with the stock functionality is that I wanted it to automatically upload images to my samba fileserver at home, rather than some weird tablet/cloud service. Having some way of printing to my network printer would be awesome too. I also like the idea of having a tiny, relatively cheap, long running deaddrop wifi hotspot on batteries. Any idea of how long you could run it for from a button battery? Could you create a half decent mesh network / wifi repeaters with these taped at various locations? I could imagine a wifi hacking linux distribution like xiaopan might be quite fun too, or something with tunnelling / vpn that can connect to a hotspot and make it safe. If there were some way to add a few sensors to it without making it much larger / power hungry, that could be really cool, especially considering how much space you have for logging. I'd like to see if one could be surreptitiously built into a usb cable, or wall wart, so it's powered when the usb cable is plugged in, but otherwise there's nothing obviously special about the usb cable.
