AOL updated their Open AIM initiative to provide developers more open access to AIM's services. 

The update provides support for location services, PC-to-PC voice calling and AIM Bots as well as for developers working with the Java language or on the Mac OS X, Linux and Pocket PC platforms.

Open AIM is intended to allow companies, communities and independent developers to develop customized plugins, communications clients and mash-ups using the AIM global instant messaging network.

"Already, more than 45,000 developers are working with the AIM Software Development Kit (SDK) to bring their creativity and ingenuity to the 43 million Americans in the AIM community," says AOL Vice President for Instant Messaging Marcien Jenckes.

AOL's Instant Messenger program includes advertising space at the top of the window.
