Hi all,
it's perfectly possible to separate mouse and wacom tablet inputs,by 
"capturing" the wacom.
The major problem is that this is can only be done by using a 
non-disclosed API. I was able to make an arrangement with wacom so that 
they gave me the relevant specs, but i'm not allowed to publish an 
object with open-source. It's possible to publish a binary one, though.
The object is already working for MacOS but i haven't had time for 
Windows yet. It will be part of vibrez_pure.
