This looks like a cool idea, except that I think it will wreak havoc 
for clients trying to read filesystems in other cells.  AFS is a 
shared filespace after all.

Such a scheme for allowing dynamic allocation of additional/arbitrary 
@variables seems to require a method of exporting your @variables and 
mappings so that other cells can understand your filesystem. 
Otherwise, there's nothing standard about it.
