This issue was already discussed a few weeks ago (December 2007), and 
the last word was although MKL would not be used for the default binary, 
a link to a binary built by someone else could be added to the scipy 
download page.

Of course, you better have to make sure the license agreement does 
permit what you think it says, since your company would bear the 
responsibility for it as far as I understand it.

The one thing which I am not sure about is:  say one MKL binary does not 
work, and say I (or anyone outside your company) build numpy with the 
MKL ro debug it, can I redistribute a new binary, even if it is just for 
testing purpose ?

cheers,
