My config files in virtual domain environments look like this:

require_once 'virtual.php';
require 'standard-conf.php';
@include $_SERVER['SERVER_NAME'] . '-conf.php';

where standard-conf.php is a copy from conf.dist and the files like
www.example.com-conf.php contain _only_ settings that differ from the
global ones.
This way the only code overhead contains of a few lines for each domain (if
at all) and I don't have to change anything in the original code, not even
in the config files.

The same happens witch each configuration/preference/registry file that
needs to be different for different domains.

virtual.php is a very small file with general settings for certain domains
and some helper functions like:

function getVirtualRoot()
{
    return $_SERVER['SERVER_NAME'] .
           substr($_SERVER['PHP_SELF'], 0, strpos($_SERVER['PHP_SELF'],
'/horde')) .
           '/';
}
