all JACK clients run in realtime mode if JACK is using realtime mode.
JACK transport has absolutely zero to do with this.

welcome to the primary reason why win/mac folks love big monolithic apps
with powerful if flawed plugin APIs.

JACK sync means two different things. i suspect you mean transport sync,
and in truth that you mean more than this - tempo sync. JACK does not
currently provide any way for its clients to share a tempo (bar/beat or
meter/tempo) map.
