Well, I'm looking for something very simple, just a dump of either the userID or cid of as many users as you can grab on Live Spaces (spaces.live.com). For example, for the link http://kkaatz.spaces.live.com/ , his userID is kkaatz (duh), and his cid is -7461019932172883201. There way over a hundred million users, so let me know what your price per million grabbed users, and we'll see if we can work something out. Should be pretty simple for someone to make some sort of script for this.
