To all wordpress users, I've made a plugin that can skim a percentage of your traffic to a url of your choice.
I still haven't tested this on wordpress mu, so if you want to try it go to this url:
http://24hscripts.com/skimmer.php
This can help some people that have a lot of traffic on their blogs it basically filters all <a> tags and adds a custom url for redirect percentage.
Tell me if it's of any use something like this for you or if you can request some features added.
Cheers.
