Subsidized Water Taxis?

Buried in this NY1 story is some potentially great news: a subsidized water taxi route to Williamsburg. The Water Taxi ™ is one of my preferred routes to Manhattan (after two-wheeling), but it is definitely a) expensive, b) limited in service times, and c) only geographically appropriate to a few. It looks as though the city is trying to tackle (a). But why stop there? They could do something about (c) if they provided free subway and bus transfers.
