sounds good. did some tests with mod_fcgid. cpu-load is higher then using 
mod_php but not as high as expected.
is this the way how it the big ones do?
is it possible to show your config?

there is one sentences in the docs which sounds strange
###
Warning
Currently, only one FastCGI application of any type (AAA or handler) can be 
used for a particular request URI. Otherwise, the wrong FastCGI application 
may be invoked for one or more phases of request processing.
###
this means that only on fcgid-script per location is possible? i would like 
to have .php4 files bind to a php4-wrapper and .php5 files bind to a 
php5-wrapper in same directory. i did some tests but could not confirm or 
decline.

Thanks,
Hajo
