There is this 'insignficant' matter known as "copyright law". Vendor-created device-drivers for Windows _are_ copyrighted works. the terms of the license give permission for redisribution of those works, in *UNMODIFIED* form. Unfortunately, when you have something that digs into that work, extracts the logic, and wraps it in an interface for a different system, that is what is called "creating a derivative work". If you have been granted the right to redistribute the 'original', that right does -not- extend to a 'derivative work'. You have to have *separate* permission from the copyright owner for a derivative work. Distributing a 'tool' that takes the 'original' and automatically creates the 'derivative work' for someone is *also* proscribed, because the primary use of that tool is to create infringing works. A 'manual' tool is a subtly, but importantly, different thing. It requires the operator to initiat the overt acts. thus, as as long as there are reasonable legitimate uses, the sfoftware itself is safe.
