We operate in multiple locations, and have for quite some time now.  We use technology to bridge the gap so that teams in all locations can feel like they are together.  Google Hangouts and Facetime are the goto technology but we find using large TVs on either end make all the difference.  The teams literally feel like they are standing in the room together. We do daily standups, one on one meetings and group calls standing in front of these TVs with team members all over the world.  (we even set it up during our 4 month stint in San Francisco)
