If nothing else, it's possible to tunnel tcp over sctp. But you could write a webserver that delivered HTTP messages over sctp directly. In fact that would make a good research project for someone. And it would likely be useful, if only for the sheer amount of stuff that uses HTTP as a transport. The thing is that as an asynchronous protocol HTTP doesn't get that much benefit from being delivered over sctp whereas protocols that depend on continuous session state like ssh or XMPP or VOIP streams would potentially gain much more.
