Very nice! :-)
A suggestion: How about making it easier to get an overview over the requirements allready from the download page? This could be done through little icons (or text) right after the main link, one icon if it is BPPC/CSPPC, one if it works on Pegasos, one if it works on A1. And icons for OS 3.1, 3.5, 3.9, 4.0, MorphOS, (AROS? :-o), etc. And symbols for AGA, CGX, P96, WOS, PUP, W3D aswell.
Of course the "requirements" link should still be there for a more detailed description ...
