I think it is probably not adviseable to have the shell be that dependent
on AFS or to run commands out of the outland locker whenever someone types
the wrong command (since the outland locker advertises relatively sloppy
maintainance and security practices). I think it is possible for those
difficulties to be overcome (I could imagine caching the whichlocker
database on local disk and the whichlocker command in a package), and the
feature would probably be fairly cool if that were the case.
