So, it's basically a PHP shared hosting with source control(git)? I would try it.

It will let you seamlessly grow from shared to dedicated hosting (and back again) as needed for either your application serving or database needs.

this is pretty much what Mediatemple.net already offers with Containers for their GS (shared hosting). They don't have PHP Containers but they do have MySql Containers that are automatically instantiated if traffic spikes. I think you could really make a difference by offering killer features on demand, like isolated memcached instances, redis, cassandra/mongoDB and RabbitMQ.
