2 questions about LiveUser

Hello! I have successfully set up auth/permission using LiveUser as a base. Works great, thanks! Although the package hasn't been updated for some time, I hope there are some LU-fans on the list that can help me sort out a few questions =) 1. I do not want one user to be able to be logged in from multiple computers/sessions simultanously. Say one username is logged in on computer 1, and the same username logs in from computer 2. Then would like computer 1 to be automatically logged off. Is this possible to achieve? 2. As a security measure I want to log successful and unsuccessful logins/logouts to a mysql table (handle, date/time, ip, event). I am not so familiar with PEAR, and have tried to configure the Log and Event Dispatcher classes for this, with no luck. Any suggestions on how to get this configuration to work? Best Regards, Axel
