user directories incompatible with the mirrors
We've traditionally had unofficial stuff at http://(www.)xiph.org/~user/ but
this has broken since we went to a mirror system.
It doesn't make sense to mirror these directories, so the proposal is that we
create http://people.xiph.org/~user/ which is a cname for wherever the main user
account machine is.
To support the many existing links to home directories; we should ask the
mirrors to redirect UserDir requests.
Monty also had a significant amount of personal stuff under
http://xiph.org/xiphmont/ that needs to be similarly redirected.
