Alternative to UDP

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:

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.
