Pushing Project Professional 2007 Users’ Configurations

Have you ever had a requirement to push the configurations of Project Professional to the users (so they don’t have to go Project Server Accounts, add account, etc)?
It is quite frequent requirement from my clients these days because:
a) They don’t want to add overhead on their users
b) Minimizing the support calls

So after spending a very little effort comparing two images of clients' O/S, one with Project Pro configured and one without configuration you can see the difference in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\MS Project\Profiles\"Path"=http://servername/PWA


So I guess to push this configuration you can use roaming profile or even it in group policy so that users can't screw it up, but one of my clients checked the ADM files and this isn't an option unless you write a custom policy.
