Do you plan to expose this REST api using Twisted?

No, I want to use Django.<br>

Well, I wouldn't use a database at all (except for logging purposes only
maybe). Actually you're already using the proper terms (queue, subscriber,
etc.), so I would use a message-driven architecture:
- A messaging broker, either using AMQP (RabbitMQ, Qpid and OpenAMQ) or Stomp
(RabbitMQ, ActiveMQ)
- You have a subscriber (waiting for messages on a queue), which dispatches
tasks from the queue
- The web application sends messages to the messaging broker, which will route
them to the right subscriber
One of the advantages of this scenario is that you can add more subscribers at
runtime if needed, which will distribute the load between several conversion
servers.
You can choose either AMQP [1] or Stomp [2], each has its strengths and
weaknesses.

The reason to use a database is because I need to save the state of
each conversion task. The message-driver architecture is very
interesting but I don't have many experience with this architecture. <br>
<br>
Anyway I will take a look products you say (RabbitMQ, Qpid, etc.).<br>
<br>
Thank you.<br>
