Environment:VC5, VC6

PeopleWatcher is a small (about 2,500 lines of code) but
reasonably extensive instant messenger program. It provides all the
standard features of an instant messenger, including
message server and client systems, away messages, and
friends lists. Its open source license means you can
freely use its code to build new applications. PeopleWatcher
is easily extended over more exotic IM features, easily
embedded into existing applications.
