[p4] Finding the workspace name: is p4config mandatory?

#1 is true only because P4V is its own environment with the
appropriate settings. You had to make them at some point for
P4V to operate, so making them a second time for a different
environment makes sense.
#2 Nothing prevents that.
#3 Make is the perfect environment to do this. That was our
first method and is still in use seven years later.

No, your problem is creating one, incredibly simple, template
file which the developer renames and modifies once per workspace,
and probably never has to deal with again. All they have to fill
in is the user ID (once for all workspaces) and the client
(which could also be once for all branches if you only have
a single client covering all the branches).
Of course they will have to set P4CONFIG in their environment,
but it's strictly cut and paste from a common prototype. (Put
the instructions in the template file as comments.)
If you don't trust the developers to get that much right, how
did you trust them to install and configure P4V?

I should clarify a few things.
1) It is perfectly possible to use p4v without setting anything in
the environment. Not the workspace, not P4PORT, not even P4CONFIG.
This is how we operate today.
2) We typically want developers to be able to build on their machine.
3) The developer build is set off outside of p4v: from an IDE, or
command line "make", etc.
Item #2 implies that I don't just have a problem of setting up 1
p4config file for N workspaces on a build server, but an NxM problem
where M is the number of developers. (Alternatively, each developer
has to set up N config files.)
Granted, this can be done. It's not rocket science. But it gives you
NxM chances to make a mistake while setting up something that should
be mechanically generated (as is done by both CVS and Subversion).
When I get to a point like this I figure either I'm abusing the tool,
or the the tool is too limited.
So what you folks using p4v with large M do?
