This sort of stuff is crucial and needs to be built in.
Most instances are one user's whim away from going away. This isn't a problem as long as clients back things up and migration is easy. But, that doesn't happen right now.
Guarantee we'll see some big news at points in the future when a big instance goes down because the owner died or just lost interest.
Again, these are easily overcome, but they are issues right now.
That's a deep cut.
