 While the current code works, it is very "A C programmer is writing Go".
 This mostly applies to the support protocol code, and refactoring it to
 make more use of channels/goroutines would simplify the code.

 This ticket also encompases "general cleanup" to the code as I am not
 quite happy with some parts of the code.
