Can you identify these clients in some way, such as IP address, so that they 
can pass an ACL before authentication is requested?

Sounds like a recipe for people bypassing authentication by simply refusing to 
authenticate, and getting allowed through.

What is your purpose in implementing authentication, if you also want some 
clients to get access without authenticating?  What advantage does 
authenticating give the ones who do?
