This might be a good idea for systems that don't use encryption. Currently all encryption solutions rely on EEPROM for key storage. Distributing a reset command to a node would...

Indeed. Just another reason for people to secure their networks :)

If `send()` manipulates the message buffer in an unfortunate way, then when the compiler evaluates the `else if` it could very well match.

No, not from what I can see: 

Cool! Thanks. I will check it out at some point.

Looks good. Perhaps also encode the type for the sensor value in the payload in case it is a set/get command? So, as a consequence, also include the command in...

Hm, valid point. Perhaps a new node would be the cleanest and most backwards compatible friendly option?
