I doubt very much that Zend would evaluate a partnership like this as being, or creating a business disadvantage to the PHP platform. I also doubt very much that Zend ever had a mission of being exlusively on any one platform. That says to me they will aggressively develop PHP - and use this to their advantage in providing best of breed web scripting technologies. The real question is how this will or will/not work with ASP. Also interesting to see Andi's response to Microsoft's interview on the lab site: http://port25.technet.com/archive/2006/10/31/Talki ng-with-Andi-Gutmans-about-Zend-and-working-with-M icrosoft-to-improve-PHP-Performance-on-Windows.asp x
