The author of the blog post that started this discussion owns a software consultancy that specializes in native application development (iOS and Android). Clearly his opinion is that native apps are better.

The company I work for just rolled out a cloud-based storage system that has version control built in. The company is Egnyte. Their solution allows us to maintain local copies of our files, with version control in the cloud. So this solves our versioning issues as well as disaster recovery. Changes made at one of our five offices get uploaded to the cloud automatically and synched back down to local copies as well. Good luck!
