[erlang-questions] Any message queue model in Erlang when doing Comet chat?

[Zhuguo Shi]

Hi Perter,

For the moment I store all the messages in database with a timestamp, also I
store the timestamp that every polling connection last received messages.
Before every polling connection established I check the timestamp between
message and the polling connection so that I can know what messages that
haven't been sent yet.

It works well in most conditions but I want to find a reliable way to solve
this problem, like a message queue.
