I have now 3 eventaware jcs caches and 1 eventaware MRU cache and 1 MRU cache by default...it
got 
out of hand :-)

It indeed almost seems the more robust I make it (even with a skeleton generator creating
an entire structure
based on best practice), the more they try to break it :-)...no not entirely true.
The only problem is that it abstracts the basics even further, and since we are outsourcing,
they tend to sometimes
forget what they are really doing and think about it. OTH, large sites are running fine for
months and this wasn't the case before I tried making it robust. But I get your point :-)
