I didn't know SCTP since you've mentioned it and have some
questions:
1. Is SCTP TCP compatible? When a server provides SCTP protocol on
port 5222 for example normal TCP clients can still connect?
Nope. Or yes. It depends on what you're asking for. "port 5222" is
transport-protocol specific, so SCTP, TCP, and UDP can all co-exist
on that port, but the server needs to listen to those ports
independently.
SCTP is also message based, which means it can cope with stanza ACKs
by using one message per N stanzas, but on the other hand it means
it's very different to TCP.
I don't think it's a solution, as such, and the multi-homing/mobility
capabilities that have been mentioned exist in several forms at the
IP layer, such as MIP6, and perhaps most interestingly HIP.
