rampancy: The only potential hiccup I could imagine for that game is that Monolith (the developers) are now wholly owned by Warner Brothers. But Disney owns both the IP and original publisher, so I'm guessing that the rights to distribution and the source code would more than likely still rest with Disney.
Tron 2.0 used Lithtech Jupiter (the same as NOLF2, IIRC), and has Gold status for WINE 1.7.32, so I'd wager that a Mac/Win/Lin release is possible.
No hiccup at all. The game is published by Disney on
Steam. Well, there might be a hiccup, as the game's Mac version was published by
MacPlay. It also doesn't help that the game is Windows-only on Steam.
