Open Questions
Hardware
- None of the Pycom boards seem to ship with an RTC or EEPROM. How
difficult is to make a board that incorporates these features?
User interface
- What does the user interface look like?
Protocol
- What data structure makes the most sense for the address book, balancing
usability with memory and program space requirements?
- How should the address book deal with nets?
- How should network reliability be handled? The system right now defaults
to a UDP-esque model; would making it reliable require too much bandwidth
or dwell time?
Security
- Many of the cryptography functions will require a solid RNG, but none
of the platforms provide support for this. How do we provide a useful,
secure RNG for these functions?
- What about sampling from an unconnected analog pin and putting this
into SHA-256 to provide some sort of source?
