[OTR-dev] New OTR Protocol draft: please look over

[Greg Troxel]

I suggest considering adding an id field to fragments.  Right now
fragments can be misassembled if the transport doesn't actualy do
in-order delivery.  The reassembly rules protect against this if n is
different, or k isn't K+1, but don't do so strongly.  Just having a
fragment id and incrementing it and requiring that it match would
help.  But, this may not be worthwhile because lack of ordering would
perhaps cause so many other problems, and it does take up space.
