PHP Business Pack

Hi, Somthing that a lot of people have been asking for in various places is reasons for using PHP commerically. I thought that I would try and gather as much information as possible together and put together a bussiness pack on why to use PHP commercialy. What I would like to include is: - Costs of Development/Deployment - Comparing ease of use/speed against other scripting langs. - PHP in a commercial enviroment - Scaleability (Please no application server stuff) - Some benchmarks - Case Studies of existing solutions - Anything else anybody thinks is relavant I think if we got this into one place at either zend.com or php.net it would help a lot of people. If you have any ideas for things to be included/links to good articles could you please email them to me and I will make a start on it and see what I can come up with. Im mainly sending this to try to get a bit of a brain storm going to see what people think would be useful in a pack such as this. Cheers James
