OK - this explains.

The branding and the stats are an important reason to keep some level of centralization (which is a 
problem of R which always comes up, as the mirror system is completely decentralized and it is 
effectively not possible to get any reliable figures).

Just an idea (and no idea how practical or even possible it is): if all downloads are *managed* by a 
central server (i.e. requests for download go the the central sever which then sends the request to 
the closest server, the download manager could keep stats of downloads, while the whole website 
would be available at different servers.
