We designed NOLO with one base station for two reasons:
1) Portability and easy setup are important for Mobile VR users. Having one base station which you could put anywhere on a table or a bookshelf in front of you and start playing right away is the more ideal than having to install two base stations in a certain way.
2) We agree more with Oculus & PSVR’s take on the ideal VR experience settings for average users (front-facing). However, we do understand that many SteamVR games are designed for a 360 degree full tracking with multiple base stations, and occlusion issues sometime interfere with the gaming experiences. We've received many constructive feedbacks from supporters like you requesting the ability to add one or more base stations.
For this Kickstarter campaign, the product we ship won't have an additional base station, but we'll optimize the design for the possibility of adding in the next generation, and try to offer add-ons in the near future :)
