displaying a splash page to a 1st time visitor arriving on any landing page (not just the home page)

I would like to display a splash page (or perhaps just a modal window) for users who are visiting my site for the first time. This splash page will display them with routing links so they can be directed to the audience specific section of the site. If they are home users, they will click a link for "Consumer". If they represent a business, they will click the "Business" link.

This module seems like it could figure out if the visitor is entering the website for the first time from any landing page (not just the home page) and display the splash page. With some cookies, this shouldn't be too difficult to implement.
