web service authentication - user tokens

Hi:

Im trying to replicate functionality similar to Google or Backpack 'API Keys' for authentication. I am using ActionWebService for several web services which I am exposing for external applications however I would like to provide some form of authentication. Has anyone done or seen this done? I have searched and cannot find information specifically in this context.

thanks for any help Ryan

It's just a hash of some unique string, like the domain, username, etc plus maybe a timestamp thrown in.
