When I use a server-parsed HTML file, the includes get all the proper %ENV variables one would expect from CGI (including REMOTE_ADDR). Either rename all of your HTML files to *.shtml, or add this line to httpd.conf (this is how I do it):

AddHandler server-parsed .html .shtml

In fact, I recall having standalone CGI perl scripts that eventually became includes in my HTML pages, and no modifications to the scripts were required for it to work properly. Of course, you won't be able to do POST forms through includes, only GET forms (as far as I know).
