Questions regarding distribution of PHP modules as binaries

Hello, all - I've got one more question for you all, which I don't quite understand. What if, say, I'd like to develope an application which requires the use of, well for simplicity, some SSL functionality. I would distribute my PHP application, but then would provide compiled modules for each specific PHP version which I expect my application to run on, for use by the client to include them as a module in php.ini, to provide that functionality. As it currently stands in the licensing behind PHP, am I legally allowed to do this? I understand that this is an unorthadox approach to software distribution, but it's just an idea that I had. If someone who knows PHP's licesnsing deep down wouldn't mind taking a minute here telling me what I can and can't do in this respect, I would greatly appreciate it. Thanks! -dant
