@Edent I missed this post from at the time but @andypiper (as one of the few people I'm still connected with on foursquare/swarm) mentioned it to me at FOSDEM. I always thought it would be nice (and not overly complicated) to have an OSS equivalent so good to see someone's on it :-)
Now I just need to find some time to play with it!

@sxa @Edent I'd definitely like to see whether we can make a more complete project here - this is a fantastic starting point.
