[p4] usefulness of a depot other than a top-level directory?

[Tim.Miller@Reardencommerce.com]

Hi,

By default p4d creates a depot called 'depot.'  You can create other
depots (and delete the 'depot' depot).  But I'm not sure (other than the
spec depot) what the benefits of a depot are or how to use them to
advantage.  Or should I just think of them as a top-level directory.

To keep pathnames short, I would like to create depots like this
(below).  Is this a good idea?  A bad idea?  Pitfalls?

Thanks,
Tim

//app1
	/main
	/branch	(full dev&sub-project branches)
	/rel
//app2		
	/main
	/branch	
	/rel
//user		(sparse task&defect branches, prototypes, non-production
stuff)
	/jdoe
	/jsmith
//mktg
	/fluff

etc.
