Route optimization.

Is there prior work or examples on setting up a router to perform  
route optimization for customers (such as using traceroute, etc.)?  I  
recently came across a vendor that has implemented a Cisco appliance  
that does this . . . it watches customer traffic and then sets about  
trying to optimize the route the customer's traffic takes.
