WordPress MU

First of all let me explain what i'm willing to do with this, maybe i'm going the wrong direction and there's a different solution.
What i'd like to do is to have all comments related to a specific *page*, let's say the default About Page, to be displayed in my default user theme homepage.
Would be nice to have a list of generic comments on each user's blog, something similar to myspace comments and i was wondering that pulling some About Page comments on home would be the easiest way. Am I going the right direction? Is there someway to let users add comments directly on the home of other users?

Maybe if you set that page as the default home page...

the main problem is that i cant find how to display those page comments while having a loop in the same page template.
