Provides classes aimed at making the process of using the client-to-client protocols involved in sending files (via "Send File" and "Get File") and "Direct IM" connections. Also provided are classes to aid in the use of the AOL Proxy Server, a rather new feature of WinAIM, MacAIM, and iChat that allows two users who are both behind a firewall to make direct connections (like for file transfer) even though neither can accept incoming connections.
