If you use the sourceforge, the files in CVS are automatically
made available via http by the CVS web interface. I think a
web page could be constructed that always points to the latest.

You could do this by launching any of the viewers in polling mode.

Make a sourceforge project and add a link to it from "Ldraw Utilities"
page at ldraw.org.
This sounds like it may complement the functionality of the mirror.ini
file we developed a while back. It also shares the same maintenance
problems.

Perhaps a sourceforge project could hold both.
Enjoy,
