develop checkin module for social engine, using either facebook or foursquare checking.

I have a lead that requires a 'check in' module developed / implemented for Social Engine. I've chatted it out & they're happy to leverage Foursquare or Facebook Checkins for this. I'm way too stacked to go rummaging around in frameworks that I don't know, so am looking to get this managed and delivered here. You have anybody with this experience?
