Copyrighting PHP, MySql, Apache,perl etc...

Hey, Was just going to the php.net site to reference the manual (always a good thing) when I absent mindedly typed in "php.com" instead....which brought up a nice site, worthy of our support, but not really what I had in mind coz its more focussed towards children, medical homes etc than the programming language PHP. Which brings up a little question, any idea of whats ZEND's (or anybody else that matters) opinion of using PHP in a domain name? eg: my-lovely-php-and-apache-website.com As you can see above, i mentioned apache too, any ideas of copyright issues for apace,php,mysql,perl etc etc? The reason I ask is, because I know Sun had a problem with a lot of sites using "java" in their domain, and sites like javachat.com, javalovers, realjava etc were contacted by Sun and told to change the name but use the domain as a pointer......for now. I could also of course reference microsoft's products, but those ************ want to get paid if someone even mentions "windows" on TV in books etc... so we know where they stand. Cheers, -Ryan P.S If MS did get their way and "windows" got copyrighted, I bet they would have grabbed a dictionary and tried to copyright the whole damn thing...starting with "the" or maybe "a" :-)) God, I really love MS bashing.
