I've been being good about keeping my multi6 advocacy off of nanog, but I
have to correct here:  SCTP can be used as a full replacement of TCP as it
is a strict superset, it also can replace UDP for many applications.

As soon as the SCTP TCP-like API is finished in the Linux kernel SCTP
implimentation I'll be making the minor changes to a few apps (lynx,
openssh, and apache for starters) to demonstrate how easily TCP
applications can be transisitoned to SCTP for multihoming support (SCTP
has a number of additional advantages that would be useful, such has
multiple streams which would require more then a simple search and
