Logistically I prefer to run the checks before it gets to the browser  
(i.e. via Makefile as the first step of build-package-deploy in a  
complicated (read: mature) in-house development environment) simply  
because it shaves precious time off the edit-build-test-debug cycle.   
But that's personal preference, works styles vary.  The concept is  
spot-on as far as I'm concerned, and I see no reason why the same  
underlying tool couldn't be built to suit both environments.

(Thanks for asking.)
