gregsblog writes "Today is a historic day at AOL as we announced a software development kit for AOL Instant Messenger. Open AIM will empower you, as the developer, to write custom clients and plugins. For now, lets concentrate on the Open AIM SDK and get into what it can do for you. First, the development kit is written using COM, so plugins and custom clients can be written for Windows in languages like C++, VB, C#, and eventually J-Script. In the near future we will have solutions for LINUX, MAC and Windows Mobile devices. Why is this important? We now have a solution to provide all AIM users and consumers to build their own IM clients and to extend the features of Triton via plugins. Of course all of this is free of charge. How do I get started? Well my team has provided a quick start guide, and tutorials, in addition to numerous coding examples, from the simple to the complex. Our examples are in C++ and C#. What are the limitations? Basically anything goes, with the exception of writing multi-headed clients."
