Want to access user-level license information re: an installed managed application

[Rainmaker]

Is it possible to access a list of users who have been granted a license for an installed packaged application?  I have been unable to find an object where this information resides.  We need to have access to this information to ensure that certain functions of our managed app can only apply to licensed users.  

Ideally, SFDC would maintain a list of individual licenses (an obect that points to a user and an installed app "License") that we can access.  Does this exist?

Thanks in advance for any insight!

Check out the isCurrentUserLicensed method.  Would this meet your need?
