I believe that there is a bug in the >compression, since certain files cause it to act radically different. I'm not sure if it's a bug, but it could be. Large strings of 0 bytes make it *really* slow. I haven't reversed engineered it to find out why (violation of license agreement, and anyway more importantly I haven't got a working debugger 'till I buy the newest Macsbug :-). If somebody's got practice with data compression, they might try writing a custom compressor. Aladdin has docs on that which they kindly sent me via e-mail a while back (no, I can't redistribute them, but you should be able to get them just by asking). Maybe someone out on the net could implement one? (I'm planning on trying the LZ-based algorithm from Australia which is s'posed to be really fast, when I have free time this summer.)
