I would definitely support a linux port. I just recently started playing ToMI because of the mac port available, and now that I can play at work, it would be nice to be able to play at home as well (/me runs mac at work, linux at home).
Wine really isn't an emulator, its an implementation of the windows api for linux (and mac, *bsd, ... etc.).
Also, IMO, people who run primarily linux also hate DRM, so it would almost be pointless throwing up a linux version with DRM. Although I have had no issues with the DRM of ToMI yet, and applaud the developers for not using some of the crazy systems other developers use, I can see that being a reason not to buy any of these games for linux users.
That being said, I would grab a linux version the moment it becomes available, DRM or not
