Personally, I don't see why it can't be done in the Software forum if it is still BYOAC related. The software forum has been used to discuss DOS, Win 9x, 2000, and XP (Not much Vista related yet). There have been linux discussions before as well including topics not related to BYOAC. Linux drivers, Frontends, MAME builds have all been posted to the software forum. Adding another forum or place to look seems like a waste.
I say do a trial. There may be more linux discussion at the beginning, but if the traffic keeps up and overwhelms the Software forum then ask Saint for a separate forum. If you want more people to be aware of Linux, then have everyone together so that others can be educated instead of isolating the forum.
