This type of setup is from two production systems running on the same box. The second system was based off of the first, and so has many of the same module names.

As we work towards a new release of each system, we must be able to demonstrate changes made without affecting the production system. Hence the need for the "test" versions.

I wanted to avoid basing the number of apache servers running on the number of applications running, as each server is one more thing to keep an eye on.
