Multi-Site to Main Host?

Hey guys! I’ve used wordpress in the past for lots of things, but with 3.0 I’ve set up the multi-site options. Everything is up, running, and peachy. I have one addition though that I’d love to know if there is any easy way to do.

I’ve got a few different blogs on a personal site, tutorials, tips, etc, along with some other friends who all work on the same projects. I’ve already given each of them their own blog.

Is there a way to make all the posts from zzz.com/aaa, zzz.com/bbb, and zzz.com/ccc show up on the front page of zzz.com?

Suggestions? I’d rather not have to write a plugin for it if I don’t have to. Cheers folks.
