Hi Bill,
I am not on the core team, but I am curious what you mean by "I know this has changed" -- do you mean you think the requirements have been reduced or that they've been increased?
The page you linked to seems like a reasonable list of minimum requirements and should be available on almost all cheap shared web hosts. And I can't imagine why they wouldn't work anymore with Concrete5.
But I don't know for sure, and am just trying to help clarify the question (and am curious to find out myself if they have changed).

Hi Jordan

I am clarifying with Franz and the team since one posting states one set of requirements and the link posted above is really really old. For instance, you need MySQL 5.x not 4.x. I had asked Franz in the IRC Channel and he asked that I post it here so it can be verified and corrected and now the page isn't there..HAHAHAH

Will let you know when I get an answer.

Bill

I would like to know the best case scenario for requirements, not the minimum that I can get away with. i.e. for best results server that supports blah blah blah.

I would like to run Concrete 5 in the best case scenario. Maybe it runs better with PHP 5.1 or 5.3.3 or whatever FastCGI on or off? All the variables to making using this framework to be the best experience - That's what I want. min. requirements only tell me what I can get away with.
