I am currently using a shared hosting web server, and am trying to set up a queue system which my main web site will post messages to. Then I will use something else (probably a cronjob) to process items in the queue.
I need something that is secure, so that other users on the machine cannot use my queue. The memory footprint should be as low as possible. Also, it should be easy to install without requiring admin access - I should be able to install to a custom directory in my home folder on the server.
RabbitMQ looks good, but it requires Erlang, and I haven't found out how to install and set it up without root access. Things like beanstalk, gearman do not seem to support authentication.
Any suggestions?
