It's on the roadmap.
I'm not aware of any 3rd party software doing it. It would be a nice idea for a project (AMQP bridge for JMS)
By "AMQP" do you mean AMQP 0.8, 0.9, 0.10 or 1.0?
0.9 is hugely different to 0.10, and 1.0 is radically different again. The spec was more or less ripped up between these versions.
AMQP is a very complex spec to implement which has provided a barrier to it's adoption. As of now there are only two implementations of AMQP which are committed to continue with AMQP: RabbitMQ and QPid, and they implement different versions.
That's a tiny fraction of the messaging market.
IMHO there's a huge question mark over whether AMQP is going to go anywhere. However, if it does and becomes popular we will most probably implement it.
Thank you so much for your wonderful and helpful responses!
I have been having trouble finding a definitive list of the differences between AMQP 0.9.1 and 0.10, do you know where I could find such a list?
Not sure a definitive list exists.
There are a lot of differences. Your best bet would be to read both specs and you will see what I mean.
Then you can have further fun and read the 1.0 draft spec and note how it's hugely different yet again
