Possible to have multiple JACK servers?

I’m trying to find out if its possible to have multiple JACK servers running while using it under Asterisk.

From what I understand you would run JACK server then have the JACK or jack_hook application in asterisk connect to the server. The thing is, I would like multiple calls to use jack separately. I would be using them to output the audio from a meetme conference but would like multiple conferences to be held but not have the audio merge together( which would happen if I used one server? or could I use one server and it be able to handle different sessions?).
