First of all, I think trying for a Linux version of Biab would be highly wished for. I have one computer running XP Pro for Biab, and another one running the latest version of OpenSuSe's Linux: Version 11--free download like all the rest. The reason I mention this is that it appears to be the most stable and functional version of Linux yet offered in the free arena. Put it on several weeks ago, and it has been stable, even after I 'tweak' the system to be able to do all the audio things I want to do. However, as concerns Biab, there are some issues to consider. I'll give you a short list of my experience with Linux, music apps, and Biab on Wine.

1. Wine is great...for some things. Yes, I've been able to get Biab 2007 to work on it, but there are a number 'gotchas' with it. Plays fine, and at full speed, since Wine isn't really an emulator. Recording presents some issues, though.
2. Being a capitalist on tuesdays and thursdays ; ) I can see a high degree of down-side to producing a version under any Linux. Free software. Reason is that PG Music is about the best in the entire software arena in the area of user support. I would hate to lose that!!! Yeah, some folks will pay, but not all, and that would seriously cut into the bottom line. Also, the version problem also has to do with the compiler version that they would use...You can build in some backward compatibility in that regard, but you really have to get in and fiddle to make that work. Then you would have to ship it as source code so that it could be re-compiled on anyone's version...aye, there's the rub!
3. If you are going to make an attempt to run Biab (Windows version) under Wine, then you probably want to use OSS instead of fooling with Jack or ALSA...There is a world of headaches there, which have not, to this date, been resolved.

There is a lot more to consider, but maybe we can find a way to determine what we really need to do under Biab, and what we'd be willing to forgo. In short, if all you want to do is use it for playback, you CAN make that happen now. I've done it. Good luck with this, and hope something good comes out of the thread you've started here!
