True, I realized after posting this and thinking a bit that things got a 
bit muddled in this thread. I'm mostly concerned about the publisher. 
The server part I guess is easier to port, though I also suspect less of 
a gain on the short term.

That would be good. I wonder how this interacts with things like error 
handling, though.
