I apologize, I wasn't subscribed to this forum and didn't see this thread.
DreamCompute, will be our public cloud computing service based on OpenStack. It will be an unmanaged cloud meaning you'll have the ability to configure everything you want. For example, you'll be able to launch servers with a choice of cpu/memory combination, operating system and have full control, including root access. We'll also provide you with completely customized network configuration options. Create multiple networks and customize the routing between them (imagine a setup with web servers being accessible on the public internet but a group of database servers on a private network with security groups configured to only allow access from specific machines).
Of course there's a lot more, but here's a sneak peek at the DreamCompute Dashboard.
And there's a great demo overview video of OpenStack available on the OpenStack site that will give you a pretty good idea of the features available - http://www.openstack.org/software/
