module proposal: BOSH

[Adam Michaels]

After much headache with Ejabberd and some internal discussions, we 
talked about Nginx supporting the BOSH protocol. This would allow simple 
creation of scalable instant message systems and anything else that 
requires stateless connections to act statefully.

http://en.wikipedia.org/wiki/BOSH

Nginx would hold 2 client connections and create a persistent connection 
to upstream servers. To even begin to make this possible, Nginx would 
need to support persistent connections to upstreams. What is the status 
of that feature? Its been listed on the feature request page in the wiki 
for a while.

Anyone interested in seeing this?
