I am leaning towards making it open source (or at very least make binaries available), but I have to complete the current rewrite (cleanup) so it is more userfriendly and ironed out first. Current code is not one that I feel has all the options that a complete engine should have. Also some choices I did when made first version was not the best ones so doing some changes. Got a bit sidetracked during current rewrite and had to put it off for a while but I am getting back into writing it.
