There are at least 2 mirrors that I know of, and I can probably find 
several more by digging in logs.

root@tutankhamon:/var/log/fifologger# grep 'cdimage/.*arch-latest' 
rsyncd_2007-04-01 | wc -l
23

root@tutankhamon:/var/log/fifologger# grep 'cdimage/.*current' 
ftpd_2007-04-01 | wc -l
3
root@tutankhamon:/var/log/fifologger# grep 'cdimage/.*arch-latest' 
ftpd_2007-04-01 | wc -l

So yes, these symlinks are used by both rsync and ftp users.

Anyway, I can look at what kind of http redirects we can offer, and how 
they would interfer with the cache redirect stuff we use. Chances are that 
the updates would require superuser privilleges on half a dozen machines 
not involved in the cd building. So most likely, no.
