PHP4 with PHP5 on same box

[chris# <chris#@codewarehouse.NET>]

Greetings,
 While I know this subject has been covered previously on the list(s).
The references I found while searching were fairly dated (04).
So it appears that that having parallel installs of both v4 and v5
is quite possible. What I would like to know is if this is still
possible and a relatively painless process. I have some 50 boxen all
running BSD 6.2-CURRENT Apache 1.3-CURRENT and PHP4.4.6 (soon to be 4.4.7).
So before I upgrade the farm to 4.4.7, I was hoping to /also/ install
PHP5 as well. While I am an avid PHP4 developer/user/lover. Some of
our clients are groaning about the lack of PHP5 support. Frankly, I
wonder why they don't just develop in Java, as they would enjoy a
very similar environment. At the same time, if it's a relatively
safe/stable environment having both.
I see no reason not to provide both. :)

Thank you for all your time and consideration.
