I'm adding more features to http://reverseinternet.com/ project of mine. In particular I'm looking to add more IDs to link websites on. In short our crawler downloads pages from pretty much every domain on the web and looks for affiliate/network ids there (like pub-xxxxx, or ua-xxxxx, or aaa.bbb.hop.clickbank.net) and stores these Ids in the database. You can then view all websites that have certain ID on them (find other websites owned by the same person) So if you know of a network or any other online service that works by putting a piece of code on HTML page that has a ID that identifies the user - post here or PM and I'll do my best to add tracking for that ID in the upcoming release. Each person who suggests an ID that I wasn't aware of will get two weeks of free premium access to reverseinternet.com
