Amazon's SQS (http://aws.amazon.com/sqs/ http://aws.amazon.com/sqs/) is a nice queue implementation with a very simple API for widely distributed systems. See the boto Python AWS library documentation for example usage: http://readthedocs.org/docs/boto/en/latest/sqs_tut.html http://readthedocs.org/docs/boto/en/latest/sqs_tut.html. Google's App Engine task queues are also very easy to use as the workers are just normal URL handlers in your app and the payload is standard HTTP data. See Python documentation at http://code.google.com/appengine/docs/python/taskqueue/ http://code.google.com/appengine/docs/python/taskqueue/ and Go documentation at http://code.google.com/appengine/docs/go/taskqueue/ http://code.google.com/appengine/docs/go/taskqueue/.
