During this weekend in PyCon India I released Retask 0.4. You can install it from PyPi.
Retask is a python module to create and manage distributed task queue/job queue.
It uses Redis to create task queues. User can enqueue and dequeue tasks in the queues they manage. Each task can contain any JSON serializable python objects. We use JSON internally to store the tasks in the queues.
We are working on one C library and one for Go. With these one can enqueue tasks in from a system written in a different language and execute it in a worker with a different language.
