I provide a link at the bottom here for the Inventory Solution User's Guide, which will cover the Application Metering product from a technical perspective.
But first,
from a broader perspective, I'm reading this White Paper right now by Nelson Ruest and Danielle Ruest:
http://eval.symantec.com/mktginfo/enterprise/white_papers/b-whitepaper_stand_sys_management_2006-01_en.us.pdf
This would be a good management read, but isn't specifically about Application Metering.
It talks about the role of IT, the importance of standardization, and how IT moves towards an automated environment. The concepts they talk about there may help you address the core issues of
why you need blacklisting. For example, maybe the users have too much control. The white paper talks about principles like "All IT systems are corporate systems." If you propose blacklisting, you'll have to prove the point that the system does not belong to the person, it belongs to the company -- and not just that it belongs to the company, but that IT is the only group purposed with controlling it.
Principles mentioned in the white paper like "Lock down all systems" and "Standardize all configurations" (which sound extreme) may also help your case. It draws on research by the authors and also from secondary sources like Gartner Research.
Application Metering is part of Inventory Solution 7.0. You can read the
Altiris Inventory Solution User’s Guide, Version 7.0 here:

Don't hesitate to repackage the technical information you learn in the User's Guide as a PowerPoint presentation or document for management by applying business applications specific to the environment you manage. That's what I'm doing to show the applicability of CMS7.
