Potential bridge: OSM and Space Syntax boring

Jonathan Crowe came up with this video down here (via OpenGeoData). It's pretty impressive how collaborative people can get and share public datasets on streets information around the world. [This video here is more surprising though]

Whenever I hear about the OpenStreetMap Project I can't help thinking about Space Syntax. Hand drawing an axial map is really boring and takes a lot of time too! The point is: Does anyone have any idea on how to convert OSM data to space syntax softwares?
