Django & Orbited - pushing messages

[P.R.]

Hello,

Currently I'm working on simple chat. I chosen Django, Orbited and JS
technology. I used "Server Component" from this article
http://cometdaily.com/2008/10/10/scalable-real-time-web-architecture-part-2-a-live-graph-with-orbited-morbidq-and-jsio/
.. and my question is: what is the best way to push message to the
DataProducer from Django view? And one more, somebody told me that
efficiency of MorbidQ isn't so good for huge transfer (I mean 100k+
users), has he right? Maybe better choice would be RabbitMQ?

Thanks,
regards.
