Take a look at our recent project - SockJS:

You would still need to write a bridge between RabbitMQ and SockJS,

RabbitMQ is surprisingly good at handling large number of relatively unused
queues. But if you want to keep them busy and push messages often -
well, that's another story. I think you should expect that a single rabbitmq
box should be able to output around 30k msg/sec. Probably less with
a large number of active queues. But this really depends very much
on your access patterns.
