Any good affiliate fee deals out there offered by hosting companies?

I realize most here are host, and thus would not send traffic to a competitor for affiliate income, but some here are not host and may have.

For those not familiar with the term, an affiliate deal is one where you as an affiliate have a link on your site that sends your traffic interested in hosting to a hosting company. If people sign up for hosting, you earn some sort of affilaite fee.

If you are a host, how has it worked out for you? And what's a typical deal like; i.e. $X per signup, which equals X months revenue, etc. ??

So, anyone have experiences or opinions on this to share?
