[p4] [Newbie]: Mapping one depot to multiple locations in same workspace

Here's my guess:
If you open //tools/NAnt/doit for edit, I think Perforce only stores the
fact that the file is open on the named clientspec (workspace). Which
one would that be? There are three to choose from. Which one gets its
file permissions changed to read-write if you open with depot syntax
instead of local file syntax? Removing the ability to use depot syntax
to support this would be a bit messy, I think.
The opposite case is similar: mapping multiple depot directories to one
local disk directory. If you add a file using local disk syntax, it
wouldn't know which area of the depot to add the the file to.
I have a ton of shared tools, but they are in a shared development area
available to all projects, usable by execution "PATH" or by well-known
location that includes an environment variable override for the path
prefix. I'm sure you have a good reason not to do this. I'm glad I
