As you guessed in your question, MP support is much more VM-specific than app-specific. Tomcat doesn't have special coding to preclude or support MP machines. The 1.4.2 JVM supports MP machines to varying degrees, depending on the hardware. For example, we have some fairly big (up to 32 processors) Solaris servers and the 1.4.2 JVM on Solaris effectively uses all processors. I don't know if the windows implementation is as good. >2.

Have have others done something That's one way to go. But you could also just set up completely different tomcat installations, which I would do if disk space is not a problem. After all, you're going to remove the docs, examples, etc from each installation so it will be pretty small. You will save the [admittedly minor] headache of having a less-well-supported tomcat configuration (one with CATALINA_BASE != CATALINA_HOME).
