Looks really great!
Being that for my Ruby on Rails developement I'm planning to learn jQuery, I would have liked more it over Ext JS 4, but sure you have good reasons for that choice (and every choice will make someone popup with a "I would have preferred that...").
The only point listed that I would have loved to see from 2.0 is I/O limits for VM's, but I understand that something has to be delayed.
Minor issue: the "Commitment to Open Source" paragraph would love be titled "Commitment to Free Software (FOSS)" instead, since I firmly believe in the importance of Freedom in software.
Hope KVM will become more and more rock solid, because Proxmox project really rocks, and you are doing a tremendous job.
(btw, sheepdog sounds really interesting)
