davidnewcomb approach above makes sense.

I'm basically looking to create a system where persons can register/login and access specific services.Having looked at the code reference, it seems i should be able to copy the requisite core class as Tim suggested above, create the appropriate module to handle users and sessions. So far so good. Is there an easier way? The default admin class is a huge thing and the API does not seem to have a way to just extract the functions i need.
