Random Thought: Embedded Comments

I was just having a random thought today and was curious what others thought. I run a few different websites and was thinking, about a social experiment. I'm not sure if Digg will release an API. But I'd be interested in replacing the commenting system on one of my sites, with inline commenting that routes through a Digg community I eventually create, when it's launched. Driving user traffic between my site and Digg. I'm curious what others thing about this?
