A "service layer" is used to access things outside your application that you need to use. For example, a web service.

As for your current app, you can put WCF in now, then just change the address, and possibly the binding, when you distribute pieces to the server.

No advanced communications has entered the picture for me yet. I am using DevForce to extend an older VFP system witch is all single tier. At some point I will be taking the new .NET parts to full n-tier deployment, just not now.
