I don't think it will be too hard to randomize posts. If you are using Wordpress, you've got the WP loop and can pull all available post IDs.

Try it with the PHP rand function:
PHP: rand - Manual

There is also this plugin:
WP125: Easy 125×125 Ad Management For WordPress | Webmaster-Source

I haven't used it yet, but it can position the ads randomly. You could look at the code and see what it does.

There are numerous ways to accomplish this task in php. I have several options written. I would need more info on your circumstance. Check out the Affiliate Site Niche Pro Deluxe link below.

Niche Pro is in pre-launch but there are two different versions of a script included in it that could be adapted to your desires I'm sure.
