We could do that, although I personally wouldn't want notifications sent to the hotmail account I use for my Live ID ... so I was thinking instead of letting you enter in a 'notification address', we verify via a quick email, and we use that to send any notifications you want... no direct connection to your Live ID.

That sounds like the best approach - like MSDN forums use.  You can set a "Notify me if someone posts reply" to xx@xx.com

Naturally, if you want to get jump out of box - Allow some kind of Rx framework editor so we can enter our own where clause and the Observable will only get posts we want (i.e. filtered on name, or date, etc).  Then maybe create a google gadget and vista gadget.  An email would be great.
