This is an interesting script.  However, I'm wondering if it would make
sense to allow setup.exe to retrieve a local setup.ini (via a file:// URL)
and distribute a special setup.ini with the snapshots...  This way, the
upgrade/downgrade feature of setup could be used to install/uninstall
snapshots.  I agree that it's probably not a good idea to make snapshots
easily available via mirrors, but with the user having to explicitly point
setup to the new setup.ini file every time they want to install a
snapshot, there's doesn't seem to be too high of a chance of them abusing
this feature...
P.S. Yes, I know we're thinking of alternate setup tools, but any of them
should be able to support URL-based multiple mirror selection, so the
above should work for them as well.
