As has already been mentioned, /vicepX can be a regular directory.
You just need to touch /vicepX/AlwaysAttach to make sure it is
"mounted" into AFS.

No.  Quota is restricted on a per-volume basis.  If you want to
restrict quota per-user, you need a volume per user.  If you have
one large shared volume, there is no way to restrict quota usage
on a per-user basis.

I don't know.

I'm not sure exactly what you mean by this.  When you configure AFS
volumes, the quota IS managed by the server.  The acls ARE enforced
by the servers (with some help from the clients).  Have you read
the AFS architecture documents to understand how AFS works and what
services it provides to you?
