I was reading up on Basilisk II the other day and the Linux version can be used as a sort of MOL for 68K machines running NetBSD or other Linux/Unix.You just have to uncheck a few options and it uses the native CPU. Not bad actually considering I'm sure that someone could probably tweak the source code so that it would operate a little more like MOL and make it so that Unix users could run Mac OS applications while in Unix, so it solves any problems of needing classic support, just like Unix users on Powermacs use MOL.
Maybe this would be a worthwhile project, cleaning up Basilisk II for 68k Unix/Linux use. I'm sure if we toyed around with it something could be done.
