 ##### Motivation
 
-Authenticaton for web applications, particularly applications created for machine-to-machine use, is often an afterthought or implemented in an insecure or incompatible fashion.  We want a robust implementation of OAuth that can run on Windows or Unix systems in front of any HTTP-serving application and negotiated by clients written in any language.  These are two-party connections, so we can use the simplest form of OAuth: zero-legged OAuth 1.0a.
