Dear Eric, I strongly second Steve's opinion here: if you want this, make it option-defined, and definitely not the default option. The case study to look at is SCTP: https://en.wikipedia.org/wiki/Stream_Control_Transmission_Protocol
While an interesting and useful protocol, SCTP adoption and support is severely limited by the fact that it is an IP protocol on its own: SCTP gets dropped in 90% of implementations doing IP packet header operations (NAT, PCEF, Firewalls, 6to4 ...) Hope this helps, Best regards, Philippe Langlois. -- http://www.P1security.com Priority One Security This transmission is intended only for the use of the addressee and may contain information that is privileged, confidential and exempt from disclosure under applicable law.
