Hello,

I've read the loss bits draft [1] and the basic functionality (a single
counter per connection, ignoring the per-CID or per-tuple nuances) is
very doable.  I can set up a separate public endpoint that generates
these bits for experimentation.

One stumbling block is that the draft does not specify which short header
R bit [2] is L and which is Q.

  - Dmitri.
