I have been cogitating on this for a little while. (Especially as I didn't want to 
sound thick when replying)

Why would MS (or anyone for that matter) want multiple pointer records when one will 
suffice. My thoughts revolved around clustered servers, .net & etc In short the 
Microsoft-verse.

In reality it doesn't matter two hoots what MS do, they will still have to 
inter-operate with the rest of the Internet per se, unless you believe the scare 
mongering that with .Net MS want to make a corporate Internet which they control.

(If they did ever go that way, I'd be one of the first to join "Treehouse")

Thinking along a bit more, setting the routers shouldn't be a big issue, after all 
Cisco have been producing routers IPv6 capable for a fair while now, so surely they 
could incorporate multiple PTR records within the routers capability?
