From Steve Myers on the forums. If it works, they're right in basically having the Mac and Linux markets cornered for anyone wanting a polished sim. Will there be a market for Linux users to a subscription-only sim? I'm a bit skeptical there, but there are definitely interested Mac racers, often using Boot Camp currently. It all boils down to how much effort it required to port, and how much continued development it will require to keep the other clients working. If the majority of code is shared it could be very good for iRacing.
