Syncing My Social Networks

Ever since Google Buzz came on the scene, I've been trying (and failing) to have my status update automatically sync between Buzz, Facebook, and Twitter. This in itself is not that difficult an undertaking. The problem rose from three issues:

1) I wanted to have Buzz as my originating space. It's in my Gmail, and there's a nice Buzz widget for my Nexus One. I didn't want to start from Facebook or Twitter. I wanted to start from Buzz.

2) I didn't want any feedback loops.
