Stealing a page from Tim Bray's hymnal <grin>, I feel compelled to 
ask:  Is there solid, empirical, profiling evidence that the TCP 
substrate of HTTP is a significant bottleneck in real web 
applications?  Optimizing non-bottlenecks is a well-known 

It's nice to know that these multicast-friendly, low-overhead UDP-
based techniques exist, and I'm happy that my local 911 dispatchers 
can use Len's products to do their good work reliably, but I'm 
wondering how relevant this discussion is to most of us.

The network effect (literally and figuratively) behind TCP and HTTP 
is a terrible thing to waste.
