Catalog Price Rules based on Customer Segments

Looking for someone to create a module to add the ability to create Catalog Price Rules (NOT shopping cart price rules) based on Customer Segments (NOT customer groups). The problem with Magento (EE or Community) is that you can create a catalog price rule with customer groups, and you can create a shopping cart rule with customer segments, but not what I need. When a customer logs in with and fits a certain customer segment, I want the price to be visible in the catalog for that customer. Main criteria is that the code created cannot bog down the site. You do not need to login to my store to make the functionality work, and I will want to demo the functionality on a demo installation on your own servers before implementing the code.
