Jeff, I really appreciate the extended commentary and examples. My only request is that you could find some way to provide this same level of clarity for the 900lb. gorilla in the room -- VMware. To this date, I've not had a single customer ask me to virtualize Exchange on Hyper-V. I'm more than happy to do so for them, but the majority of my customers are already committed to VMware.
If you can't comment directly on the equivalent VMware settings and features, at the very least it would be awesome if you could get someone from VMware to post a follow-up "okay, here's what Jeff's post means for our users, with the corresponding settings and screenshots" blog post that you can then link back to from this post. Same thing for other SVVP vendors. If this post could become a clearinghouse (or you could create a TechNet article that could serve that purpose), it would be really useful for everyone. And it would end a lot of arguments with customers -- we could point them to definitive statements by Microsoft and their virtualization vendor of choice saying "this is what you need to do to be supported."
