Ormus seems to have quit. Unfortunate.
Anyway, looking at the Windows source code, a few things--
-These sources are getting only slightly less Windows-centric. Good start, but far more is necessary. #ifdef hell may not even work with the mess on our hands.
-They're never going to compile under VS2005, which is a cast-iron shame. 800+ errors say "hello." Similarly, on gcc, I can only get it to compile by mickey-mousing the CFLAGS and ignoring things that should not be ignored.
-These sources still don't work on Vista. Now, like any half-sane person, I don't use Vista (tested it in VMware), but that's still a sticking point. I'm of the opinion that a reimplementation may be necessary, especially to expand the system limitations sanely. (In my spare time I'm messing around with one.)
-New file format. Very, very necessary in the long term. I propose that a group get together and formulate this, preferably one with a lot of both scenario and code experience.
