I've been wondering about this for a little while, and would very  
much like to see more work in this area. One of the interesting  
questions is how you'd layer HTTP-over-SCTP onto the existing Web;  
Upgrade doesn't quite meet the requirement (it's a whole new  
connection). Seems like one more piece of site-wide metadata to  
advertise...
