Rackspace Cloud is (sort of) missing on your list. "Sort of", because Slicehost is on your list, but Slicehost was bought up by Rackspace, and Slicehost will eventually be moved into the Rackspace Cloud brand, as far as I know.

Also missing: Gandi.net.

The list of providers on the website is not comprehensive yet. I have a big list of providers offline that I plan to add. I wanted to get the website functional and get some feedback before I go too far. I will make sure that these two are in my list.
