Object storage is very different from block storage.

A quick write up can be found here

http://www.quora.com/OpenStack/What-is-the-difference-between-Block-storage-and-Object-storage-Also-In-what-way-they-are-similar-dissimilar-to-POSIX

If you are looking for a distributed storage backend that is integrated into Openstack that supports block devices, look into Ceph. Once it is setup as a cinder backend, you can use it seamlessly with OpenStack.

EDIT:

I thought I would add that you technically _can_ boot an instance out of Swift if you use Swift as a Glance backend. But that requires you to download the entire image before booting it.
