There should be an option to work off-line, not connected to the internet. A time restricted authorization token could make it work... similar to how a traditional license server lets users 'check out' a time restricted license for off-line access when traveling.
Additionally, cloud storage is great but it would be better if it could work more like Google drive or One Drive with your project files stored on a local folder that syncs to the cloud in the background. This would enable off-line modeling until the next opportunity to connect and sync data.
