is this just vagrant (http://vagrantup.com) as a service? How is this different/better than vagrant? Looks interesting.
The vagrant functionality is part of what we do, but we also have a hosted service and offer access control to your team. We also have a mechanism to synchronize changes between your envs
Are you doing sort of a blended app hosting/cloud offering?
What we have in the works is detecting if you have e.g. Redis and subscribing to that "addon" for you.
service 'redis', '~> 2.2.2'
