I should add that vtune's particular license towards Open Source
projects, trying to prevent any paid work from occurring on an open
source project, did change my position about it: I now consider vtune
as unfriendly to open source, as its license subtly prevents growth of
the projects using it.  I'm not usually the kind of guy that would go
on a rant about license A or B, but this one strikes me as unworkable.
This license is made by considering that commercial interests and open
source never interact.  I will thus reply to it by saying that I may
consider helping you anyway---for a fee, with a regular commercial
contract.


A bientôt,

Armin.
