The trick is to register variations of this class where the view's 
browserDefault() method each time points to a different method, or 
implement a generic browserDefault() method in the base class that 
inspects the last URL segment and maps that to a method.

Note that this doesn't have to be part of core Grok. It could be a 
separate package, e.g. megrok.json.

I've been playing with KSS in Grok and have come up with a similar need. 
While for regular browser views it makes sense to have each view be a 
separate class, it feels verbose for Ajax / JSON.
