It's a nice idea for merchant only. It's easy to create an in-house system that works like this. You put js code to your pages and it can parse the domain part (abcde.tld) from referer url and use it as affiliate id. However, your affiliate won't be able to display your link on websites which are not under your affiliate account, and they are unable to use ad serving software (e.g. phpadsnew) to manage links. So most affiliates will pass your affiliate program.
