Jason proposes Sherfari

Jason asks Why are Safari and Sherlock two different applications? following the release of Apple's new Safari web browser, and a rather visionless discussion ensues. For the most part, people seem stuck on the backend, technical nature of his proposal and not much on the UI or user experience. Where are the UI geeks on this? I see great benefit in a sort of "web services + browser" application and know I would use it more often than all the stand-alone applications.
