If you want to run jack as a non-root user, with realtime priority and
under kernel 2.6.x you need to build an additional kernel module, the
realtime lsm module (latest version is 0.1.1). If you manage to build
that module for your kernel and you load it with the proper options you
should be able to run and jack and its clients as non-root users. See:
