Twisted PB vs JMS

[jacopo]

I looked at Twisted PB for an architecture with one client
distributing some processing to several servers. Now I came across JMS
and I have seen that using ActiveMQ with the Stomp protocol there
would be a good support for Python.
Surprising I couldn’t  find any article comparing the two
technologies. I wonder if they target different problems (it doesn’t
look to me).

Is anyone able to sketch advantages of one solution against the other?

Thanks,
Jacopo
