What tech does one need to implement a switch?

• UDP
• JSON
• SHA1
• XOR'ing the 160 bits of a SHA1 hash
• handling both network events and timers (and possibly interactions with the "app" it's serving)

What does a switch need to do?

- listen for UDP packets (off a random port)
- send something to an initial seed to discover its public IP:PORT
- announce itself and try to discover other switches nearby to it
- maintain the "lines" it has active with any other switches
	- validate sender/status
	- track bytes sent/received
- answer requests for nearby switches
- accept "taps" from other switches
- match incoming signals against any active taps and forward them
- that's plenty :)
