Many, many years ago NoF ran on the Apple Mac platform. This was in the days when MacOS was a proprietory OS with a declining market share. Today the scenario is very different. The Mac OS has a unix base - FreeBSD and a growing market share. Given that once the code base was developed for one *nix variant, it would be relatively trivial to port it to other variants - Linux, SunOS, et al. This would give NoF an opportunity to grow its user base among those who do not and will not use windows.

Think about it.
