I usually achieve this via seperate context - you can reastart each app 
seperatly. And (usually) the apps don't step on each other toes and a 
broken app doesn't kill the whole Tomcat.

However. With multiple Tomcats I usually run multiple (virtual) servers. 
In my old company we used to have seperate tarball-installs running from 
/home/tomcat/<instancename>. Used to work fine as well - with a special 
initscript that could start/stop all instances, as well as a specific 
one. However, it was a update nightmare, as you can guess. Links would 
have done a fine job in that case - I guess.
