I think on wireless PGM is not a great idea unless you can implement a
congestion control method that works, with tweaks for radio interference
patterns.  PGM is 1-to-many, for 1-to-1 there are a plethora of options, my
first choice excepted it not being implemented in 0MQ would be QUIC from
Google, for long links it would be UDT.  For real lossy environments you
may need UDP-Lite and possibly a one-way broadcast channel.

I'm the developer of the PGM implementation, the project is currently on
hiatus until I have a new use case for it.  Presently I only have need to
1-to-1 channels.
