How can I watch a Foursquare venue for check-ins?

Question

The FourSquare API seems to be very user-centric: After logging in via OAuth I can see my friends check in, and which of my friends are currently checked into a given venue.

I'm looking for something more venue-centric, where I can get a list of everybody currently checked into a venue (friends and non-friends), or ideally receive a notification each time there is a new check-in at a specific venue. Is this possible with the existing V2 API?
