Well, if you could supply some more concrete information on this versioning method, it may change my opinion. There are things that will simply not work right, though, because they're 'not meant to be'. For example, the Sybase library isn't supposed to be initialized twice within the same process; If you have both PHP 3.0 and 4.0 in the same server, it may fuck up. I'm sure there are plenty of such cases, where running two versions of the same thing within the same process will cause problems. Considering the number of issues raised by using CGI binaries (almost none) - I don't think it's that much of a necessity to support running both 3.0 and 4.0 within the same server as modules. You can run 3.0 as a CGI and 4.0 as a module or vice versa, and rarely will this pose any limitations.
