In short, an OAuth is a series of procedures (Server requests, URL-encoding, sorting keys, sending and receiving data, etc.) allowing a user to give the application (script, web app, etc.) access to some functions on his/her account of a specific site, such as Twitter, imgur, etc.
Sometimes coding has the potential to unleash more coding, in a positive sense. By developing an OAuth function for AHK you would enable a great community to do even greater things, communicating with web 2.0. Most site APIs nowdays require OAuth for atleast some of the functions, but there's no current solution for OAuthing with Autohotkey. It also might enable more donationware, and atleast very useful ware, which increases the possibility for donations.
Note that this request is more of a function/library/code request than an application request.
