"30 minutes away..."

Are there any mapping applications that display all regions within a fixed distance from an input point? For example: from a given address in NYC, what are all the places I can get to in 30 minutes, via any combation of walking + public transit?
So we're moving to NYC (yay!), and my wife & I are looking for housing. We're trying to stay within a 30 minute commute from her work, and I'm searching for possible neighborhoods based on subway & bus maps.
Wouldn't it be nice, I mused, if I could type in where she works, and a tolerable commute time, and Google Maps or something would show all the places we could live within (any combination of) transit + walking distance? All the data's already there, on NYC MTA. Surely someone more clever than I has already thought of this and done it.
Right? If not...I might take a crack at it. If the answer is no, this doesn't exist, then I have a follow-up question: I bet there's an algorithm in graph theory that returns a list of verticies within a given distance from a source vertex. Where should I start looking?
