[UPHPU] Is there any PHP asynchronous messaging solution?

[Alvaro Carrasco]

I need to implement some publish-subscribe type messaging and i'm 
looking for a PHP based messaging system. Hopefully something that 
stores messages on a mysql database.

If there isn't any, i'll have to connect to JMS or MSMQ.
Does either JMS or MSMQ have a way to connect to them using http for 
both publishing AND listening?
I've read about using manta ray and the java bridge to connect to JMS, 
has anybody actually done that?
