With current JACK CVS (soon to be released) it *is* possible to run
two separate JACK servers.  *But*, that does not do at all what you
want.  The two servers each use different, unsynchronized clock
sources, so they would be totally useless for the purpose you
describe.

I hasten to set the record straight, because I fully expect many
people to have unrealistic expectations for what multiple JACK servers
can do.

Good idea.  Maybe Rui could give QJC an option to ignore connections
from a client to itself.
