Automated UI regression testing

Over the past year year or so I've been pretty passionate about trying to make automated UI regression testing easier for the Windows Mobile team. As such I helped to develop an automated system that will compare bitmap snapshots of an app's UI from 2 builds and will notify our testers if anything has changed. Other groups at Microsoft have expressed their interest in using this tool and this has got thinking of how others may be approaching this same testing challenge (or if anyone even cares about this sort of test work). Anyone have any comments?
