You might know this already, but...

The login script on my site supports Path Rewrite technology, which allows you to dynamically define a single resource connection. You can also set priorities so two resource records can compete for a single connection. This allows members of various groups to connect to resources in different sequences.

The ultimate configuration would be a full rewrite - the record references a lookup table in the config file. With this, a single record can lookup a resource (printer or disk) and map it based on the userid, OU, or group. Every user could effectively have a unique mapping, although it is more generally done by department (OU or Group).
