Brian, They're probably just requesting the logical separation of these components rather the physical separation onto separate servers. That is, use CFC-based architecture to handle database interaction and business logic, and CFM templates controlling presentation (calling CFCs to get data/content from database).
You still achieve your tiered architecture without necessarily having separate servers. However, if they want to really nail down the security, separate these out onto separate servers so that calls to the database can only be made from the CFC server - probably firewall restricted or with direct network connection through second NIC. First server (holding CFM templates) calls CFCs on second server, which interacts with database... I'm glossing over some details here, but it should give an idea of where I'm taking this.

All they have specified is that they want a 3 tier system, presentation, business logic and database. I'm trying to get some more information on what they mean by each layer. I'm assuming its IIS on one server, com objects on another, database on a third.

Are you saying you want: web server (running IIS / Apache) app server (running ColdFusion) db server (running SQL Server / Oracle) If so, look for articles on macromedia.com that describe "distributed mode" for ColdFusion. Why does the customer specifically want this?
