Isn't this only a concern/advantage for the hop between a client and a
client-side proxy?  Requests toward different hosts are going to be on
their own connections in all other situations.  Origin servers are
unlikely to see any benefits from improved compression between hosts.

The question of reuse of a connection for different authorities is
still unresolved.  I know that  this is on some people's minds, but we
haven't seen any proposals, nor do I think we're ready to go there
just yet.
