Watching the demo video, I noticed that this program presses keys for you. Typing the command "#key s" on the main causes the slave toon to walk backwards (presses the S key). I assume you can cast spells as well. There is no way to do this from the wow API, the movement and spell functions are protected.

The ability to whisper cast was removed from the wow api. Why would Blizzard allow the same functionality in a 3rd party application?

In my opinion this is BAD, because the action does not orginate from a HARDWARE EVENT like pressing a key on the keyboard would do. In my opinion, if you use this program, you are fast on your way to getting banned.
