What is Project S-Bend?  In it's simplest form, it's a mechanism of notifying a Citrix admin of audit related events that are occuring on your Presentation Server 4.5 farm.  Ok, so what is it really?  It's a Windows Service that Jason wrote that identifies changes to your Configuration Logging database (new in PS4.5) via a SQL Trigger.  When new events are written to the Config Logging database, Jason's windows service will dispatch an email to you letting you know what changed.  Here's a link to where you can read about S-Bend and download it.  And here's a link for basic setup instructions.  Awesome stuff.
