I did notice that.  Maybe I'm confused with the purpose of the _Overlay 
and _Local structure.  If I don't want the functionality to affect tickets 
themselves, how would I do that?  With subclassing, I could create a class 
just like ticket and have the web inteface use it, and ticket would be 
left alone.  However, if I create Ticket_Local.pm it will also affect the 
parts that use Ticket.pm.
