Pascal,

Thank you for reading the document. See my comments inline.

The issue with replication really is the traffic volume - you do not want to double your pain you are already having today. If future developments on the radio bring the traffic volumes to sane numbers replication could be useful, since there is no really room for retransmissions or forward error coding schemes that require interleaving.

That is over one hop.

ACK. Will fix.
