The 1.1 to 2.0 proxy is not going to help a lot, but the 2.0 client to 2.0
proxy to 1.1 internet that Adrien was talking about above is going to be
the biggest immediate win. I predict that we will see them appear before
the protocol is finalized. With a 300ms RTT on the air medium and around
10ms on the wire, you can safely expect that if a client is able to send
all requests at once so that the proxy parallelizes them to 1.1 hosts on
"infinite bandwidth" links, it would be foolish not to deploy it.
