Multiple files are not necessary, multiple "server.xml" files
(with different port settings) are. You can specify the "server.xml"
file to use via the "-f" command-line switch to (and
startup/ which are just wrappers for that script).

I run 3 different instances of Tomcat on my development machine (to
accomodate different CORBA configurations), and the port numbers are
the only Tomcat configuration that needs to change. You will need to
configure Apache for load-balancing across the Tomcat instances for
the type of use you are wanting though.
