Other popular VTTs build themselves around the cloud-based model, which does offer attractive benefits such as connection reliability and ease of setup. But things go south pretty quickly when connection to the service, the Internet itself, is lost.
Ultimately, these virtual tabletops are still tethered to the need for an internet connection for everyone involved. Mote is capable of providing a great game experience, in whatever gaming situation players find one another; from face-to-face runs over the weekend, to sessions started over of the Internet. It can run on anything that can Java applications, without the need for installation, making it virtually portable.
Lastly, if you haven't watched the video, Mote provides a "headless" mode where savvy users can setup cloud-based services very similar to what the other Virtual Tabletops offer, via services created on platforms such as Google's Compute Engine or Amazon's WS & EC2, at a lower monthly maintenance fee compared to subscription fees.
What is important to note here is that Mote users can potentially get the best of both worlds when these services are actually provided: a full-featured application that is served on a reliable host; ideally, with no subscription model at all. We're confident someone will put up such a service. If no one else will, then Idle Ideas is open to making one for the tabletop community.
None of that "paid subscribers only have access to feature X". Full features for free, on any game setting appropriate for a Virtual Tabletop.
