I'm super new to all this, and from what I'm reading so far, it seems like this might never really fly in this sort of community, but is there any idea of letting people keep all their own data?
e.g. buy the hardware and maybe download a server or share some sort of API (and pls, pls pls make it OS agnostic as best as possible) for how it's transmitted and then this could be attached to private networks that don't have an outside connection? it'd be very useful for the extremely paranoid (like .. maybe even some sort of .mil application?) or for places that may not have 'real' networks.. or very limited network capacity.
I suppose you'd also need to be able to connect to the device and either flash or program in the destination server...
anyway. just asking. it seems like the kind of thing that would be much more appealing to me.
