Well, I know this is only in 'one-half'-ontopic (so if someone want to remove this or convert it in another thread feel free to do),
but I recently asked at the European-EN-CS forums about mouse-broadcasting via software in general, and given them some scenarios I hoped they would clarify if ok, or not...

..if anybody want to read them, the thread could be found here:
Blizz CS Forum: Multiboxing and Mousebroadcasting

...honestly I was a little bit diaspointed by the general answer beeing:
This isn't really a different issue from what has already been discussed before in various multiboxing threads; the same principles apply whether we're discussing distribution of keyboard or mouse commands. As long as each action for each character is taken manually, with no automation involved, we don't have an issue with it. I'm not familiar with the particulars of the software you have at your disposal though, and answering your examples in detail would require knowledge of how the software operates and obtains various information. All I can suggest is that you review our policies once more to ensure none of its workings actively break any of them.
..because general its not realy a 'Yes' or 'No' which i would have hoped (and could have lived with), but general more vague stuff...

..nevertheless I thought I would share this...
