I'd have thought it was worth seeing if FECFRAME fits as something to 
talk about.

It is used in places. There are transport concerns that differ and could 
be highlighted  - because some uses require pre-provisioned capacity 
(aka, do not have CC), so we probably need to say something about 
managed environments.

Whether it is a transport protocol (like TCP, UDP, websockets, etc), or 
a component (like ledbat) could be an interesting first debate.

What do others think?
