Copyrights and licencing terms looks okay :)

That I dislike, sorry this must not be dlopen'ed in at runtime,
but checked in at configure time and properly linked in. Also
means that proper dependancies and packaging have to be in place.

So what is that SDK library, how is it distributed and what is the
licencing for it ? As much as I like adding a driver, I would like to
make sure the deployement is clean and there is no licencing issues.
Any pointers ? All I found was
http://www.parallels.com/ptn/download/sdk/
and it's quite silent on code availability and Licence for the
libraries.
thanks in advance !
