What can a Shammyknight Tank?

Ok, we all know that shamans are able to solo old school raid level mobs, so here's the question: What is the hardest raid mob that you've been able to tank or that you believe that a shaman would be able to tank? Just thought about this on the long drive home for spring break and was wondering if a modern-day shaman would be able to tank raid-level mobs (was thinking most likely PoP era stuff, I figure that stuff after that would just have too much punch for clerics to keep up with). And, what do you think that a shaman would be able to do to keep agro on something like that? Don't know if chain slowing (with 2-3 different slows)would be effective or if you would wind up with mana problems doing that. With spirit channeling, it might just be possible to do that, but I've never tried to do that intentionally.
Stupid question, most likely, but just wanting to try to find some things to do on days off from raiding and bored in PoR . . .
Feel free to comment or /flame on
BTW - anyone know what armors have a plate look to them, I'd like to make some pictures of my new shammyknight
PS - Samanna, think I could get my title changed to Shammyknight ! please
