On his blog today, Pierre has an interesting post that has details on some of the Oracle acquisition plans - some of which might include Zend.
There is rumours relayed by The Register about Oracle acquisitions plan, it is a quite surprising to see Zend in the list. Note that the text is not clear, but whether it is true or not, the scenario is interesting enough to think about the impacts in the PHP world.
He also comments on the "creator of PHP" tagline that Zend uses quite a bit, and how, if it were moved over to Oracle, would be "an insult".
