xmlBlaster and Activ MQ's HTTP for asynchronous notification either
require polling or a proxy that can accept connections across the
firewall. The beauty (and scariness) of mod-pubsub's approach is the
use of streaming HTTP to keep connections persistent so no polling and
no proxy needed.

I'm certain neither of those projects work well in JavaScript
contexts. It's not what they were designed for, and it's the reason we
didn't use them in the first place.

Thanks, much appreciated.

By the way, I'm not sure anyone is currently using the Python client
library in a project... though I'm sure one day someone will...
