It's bad enough that not all environments allow monitoring of TCP acks.  I 
don't think SCTP is any better of a recommendation.  If we want something 
universal, we have only plain TCP and UDP, really.  Of course, SCTP can be 
layered over UDP, but that's a hefty requirement.

Keep in mind that we have HTTP Binding, to assist platforms with very 
restricted environments.  It's okay to be a purist, when it is reasonable, 
but sometimes it is better to make exceptions like this.

In my opinion, XMPP over SCTP over UDP is too much to ask for, when just an 
element or two in XMPP over TCP will solve our problems.
