TCPM decided to prohibit that in the general case, but I could ask them to allow that in very limited environments (but it could NEVER be default on). Note - the use cases I'm hearing appear to assume very strong knowledge about the other end of the connection and the path. In that case, you probably can skip most - if not all - of the 'negotiation' options and just start using them during the SYN too. However, if you say "no, we need to confirm", then you would not be able to use EDO inside the SYN. Joe
