I don't think that's it, really. Email, chat, project management, source code hosting, video conferencing, phone/audio conferencing, etc. are all done on the web or in the cloud or whatever you want to call it. Practically every large open source project is coordinated over the internet with limited face to face time, so the concept works well at some level at least. Given that the model works in theory, it's surprising there aren't many startups trying to go the last mile to make remote working better for a general audience.
