OK.  So how do we get retransmission and guaranteed delivery?  Is there 
a best approach?  I might be able to set up Zmodem over TCP like we used 
to for downloads on terminals: two Zmodems should do great for 
guaranteed delivery (one upstream, one down), and Zmodem was known for 
smoothness of the stream and connection recoverability.  But I would 
really want the two Zmodems-over-TCP to replace the UDP, not encapsulate 
it, and Zmodem is such an old protocol that it might be extremely 
wasteful on modern wifi.

Along the way tonight I found this:


which looks quite intriguing, had never seen that before, seems like 
MIDI-over-TCP.  But I want to use high speed as infrastructure to allow 
for guaranteed delivery (the original MIDI spec is so extremely slow 
that this should be a slam-dunk!), and I haven't found that as a design 
feature in any code yet.

Thoughts, anyone?
