I'll be testing the transition from proximity as soon as it becomes available... I'm in a shop supporting somewhere between 100 and 150 developers spread out all over the world. So, just tell me where to pick it up and where to send comments and I'll provide any pain-points we experience (hopefully not many)  Thanks!  Proximity really made things easier in this shop, hopefully Nexus will go beyond that and make or development even easier to support!
