What else can I say than OK ?
Well, I didn't mean to host every and any old linux version around, that would be quite hard to update. Getting old versions of Linux-programs is usually quite easy anyway, because the developers offer them. Only big companies like Acrobat or real.com only offer the latest version. Also, big companies usually offer only 2 versions, rpm and executable for other distros than redhat. This wouldn't be very hard, but if you don't want, well ... it's your choice.
