Sure. It's one approach. You can also use Redis and txRedis -
https://github.com/rlotun/txRedis. Redis has pub-sub functionality that's
much simpler than AMQP (but not as powerful - for example you can't do
something like ACK a task). But for basic pub-sub it's awesome.

Also, keep in mind you might want to use twistd in conjunction with a
process runner (http://dustin.github.com/2010/02/28/running-processes.html).
That is, if you're using something like Ubuntu, you probably want to
run twistd using upstart
mewhere. When a client connects, you issue a task, and return
the task id back to the client. By and by the job is picked up by some
worker, and the result is stored in some persistent database, like
MySQL or Redis. Celery also has excellent integration with Django.
Hope that helps you out.

you can just write 'asserts'. However,
there are some caveats - namely that twisted is actually started in
another thread. So, if you plan to run a server to test calls against
(say in your setup_module) you need to make a wrapper around any
connection maker to use reactor.callFromThread.
Hope
take a look
at your kernel settings in sysctl and check that your fs.file-max
setting is something suitably high (this is assuming you're using
linux...).
