Yeah. In theory it would be nice if, for example, a corporate or ISP  
proxy could "manage" a bunch of WS connections back to a third-party  
service provider, but there's a lot of risk and overhead to going down  
that path, and not a tremendous amount of benefit.

I suspect most of the intermediary cases that are going to come up for  
WS in the near future are going to be server-side (like HTTP  
accelerators/reverse proxies), and they're already under the control  
of the server, so they can coordinate.
