Yes, I really want to implement this because there are requests from heavy technology users (java, ruby, etc...) for whom establishing a connection costs a lot (while it's ridiculously cheap on standard technos). You may remember the diagram which was/is somewhere in a "keepalive" directory on my site, where there was a distinction between request and session. There was also a connection handle for a server, which could be reused for other connections.

I think that will require a lot of work however, but it will eventually work.
