The application is included in Communication Tools.
From the developer:
iJames Away Message gives you the ability to provide a specific automated response based on who sends you an instant message. For example, I can set an away message for my girlfriend that says, "I love you" and a different one for my best friend that says, "yo dude! game today!"
It is still a beta product but pretty simple to operate. I welcome all comments and questions.
You may want to check out more software for Mac, such as Message+, OLK14 Message Recovery or Remove Duplicate Messages, which might be similar to iJames Away Message.
