A directory should suffice.

Do not do that. Create one volume per user, one per project etc. Volumes
are cheap. A volume is a quota (and a number and a name), not very much

What purpose are you rolling AFS out for? You should do it the AFS way
or not use AFS. AFS manages all data. And you get a lot of benefits
(like migration volumes between servers without anyone noticing, RO
replicas, seamless plug-in of new servers, seamless removal of servers,
strong authentication, neat backup, just to name some)
