Andre, I think the idea of identifying semi-persistent mirrors is a nice 
concept, but will quickly become obsolete as automatic mirror selection 
technologies are adopted.

For instance, a simple algorithm that pings a set of mirrors and chooses 
the one with the lowest ping time can be very effective and super-simple 
to implement.  Users shouldn't care where they are downloading from, 
just that they are getting fast downloads.

Likewise, the Open Content Network (http://open-content.net/) can 
download content from multiple mirrors in parallel, making the issue of 
selecting a single mirror an even more moot point.

I remember using Napster back in the day and having it display the 
individual hosts from which files were being downloaded and thinking 
that it was incredibly stupid to have the user choose the peer.  Sure 
enough, modern P2P systems now abstract away the underlying peers and 
simply work on the user's behalf to provide the fastest possible download.

Personally, I think the days of manual mirror identification and 
selection are numbered.
