@anne what if this but using a p2p protocol instead of gsm...
it could add to the low-tech vibe of the thing (although it would probably need beefier hardware, like an actual SOC with Linux and whatnot. so maybe I'll just stick to trying to make one of these into a (USB?) peripheral)
Hmm. You're going to want Datagram TLS and/or SRTP, and those are a bit heavy for a microcontroller. (And existing implementations might be proprietary.)
On the other hand, careful work on a microcontroller might add robustness to unpredictable lags. Real-time programming there has teeth.
Whoa I love the idea of pulling out a metal retro phone and saying "hey Tux what's the atomic mass of xenon?"
