Well if it's OctaMED you want, just use the PC version. I have it here (though not used it for years
there are simply better trackers out there now, not that I use trackers anymore)... But it does work in Wine so it will run on your OSX/*nix boxes too.
@Tension, that is a somewhat limited view of an Operating System... The SuSE linux install on my Athlon64 can't run the same software that the uC Linux I have installed on my ARM Dev board runs (without a recompile), but they are the same operating system no?
