Well, in general you can get the base server URL by doing the 
following:

   $BaseUrl = 'http://' . $_SERVER['HTTP_HOST'];

However, I'm guessing there must be some reason this doesn't work for 
you.  In that case, the easiest thing to do is to create special .php 
files that hold any machine-specific settings, and include them from 
config.php.  For example, in your local/config.php you could put:

    include_once('../machine.php');

and then create a machine.php file in the directory above "pmwiki"
on each of your systems that makes any machine-specific settings.
Copying the pmwiki directory from your local machine to your
webserver won't overwrite ../machine.php, so those settings would
remain without you having to change them.

As far as farmmap.txt is concerned, you can also create more
InterMap text file locations -- just add:

    $InterMapFiles[] = '../machinemap.txt';

into your config.php and it will load entries from ../machinemap.txt
in addition to the normal intermap.txt files.
