I wonder if they will allow multiple apps sold from the marketplace to run on the same instance? I haven't gone through the process yet of setting up an instance via the marketplace, but I think that it's essential that I can a.) install multiple copies of the same software on an instance and run them via virtual hosting (for example running multiple Wordpress instances on a single node and b.) allow different kinds of software to run on a single instance (let's say an instance with a bug tracker and a log analysis tool, just as a made-up example). The other thing that I find interesting is that there doesn't seem to be an API yet. I would love to be able to provision apps on nodes via an API to the marketplace. I'm definitely going to play around with it a bit and see what's possible though.
