I don't know that I have any bright ideas other than the obvious of making a list of these services and doing something like the New-Stuff package in acs 3.2, where modules can register procs that do the right thing with a central admin facility.
The challenging part will be:
- figuring out what all services there needs to be
- figuring out what the interface should be.
Ideally this would be included in the APM so that you would be reminded of these services existing (or not) when you installed a package.
This makes me suspicious of the admin interface for the ACS4 (okay, so I have been busy with client work and haven't looked at it yet... smack)
cheers,
