Using 4.0,

Is there a way to place notes that are viewable to customer once they are logged in?

For example, we use a third party system for processing orders.  I want to have a page that will show estimated ship
times for product on order, some of which are NOT on website.  I can generate content in third party system, but I need a way of presenting it to logged in customer.

Information would be unique for each customer.
