So true. I am working with a system currently with tons of "moving parts", once it's up it's neat, but there's always at least 3 things broken every time I install it. The person who created it is the de facto expert, and everyone else just relies on them to fix it or extend the more tricky bits.

It does leave one wonderful if the niftiness is worth the pain, or if there is a way of getting the good bits without the complexity.
