Why would it not be wise to allow Qtractor to read tempo from jack?
Because,... I'm not quite sure who, qtractor or some other jack transport client, must have the authority to set the tempo, specially when transport is already rolling.

As is, tempo is a static property of a session, and letting anyone else poking in it will result in some unnatural result, to say the least :) probably some race conditions are due in. I guess current qtractor implementation gotta be the tempo master at all times and thus, it shouldn't accept tempo changes from outsiders, specially while transport is rolling. And AFAICTT, you don't have a way to detect jack transport tempo changes unless it is already rolling.

But I might be wrong... (or forgetting something)
