Neal,
A network protocol that is unreliable (i.e., lacks retransmission of
dropped packets) and lacks congestion control will certainly never be a
common, general purpose protocol, due to the amount of work it imposes on
its user. Implementing an AIMD congestion control algorithm is burdensome

A bit OT, but the widespread use of rfc 6347 could have a big impact on my
work.
I wonder if it's likely to see widespread use? What are likely/possible use
cases?
Thank.

No: when dealing with blocking sockets, the OpenSSL library activates its
own retransmission timers, and the application never b

Python 3 is where it's at! :-)

Thank you. I will gladly port to Python 3 if there is interest from
the community.
Regarding PEP 3156: asynchronous use of unreliable network protocols
makes for an interesting use case. In particular, it forces
applications to deal with packet loss under some circumstances. One
such situation occ
This sounds exciting. Are you considering a Python 3 port? It might make a
nice demo of PEP 3156.

I would like to announce Datagram Transport Layer Security for Python. From
