Oh one other interesting thing I forgot to mention. JDK7 is adding a 
file notification API that integrates with the OS FS notification APIs. 
We could probably have mostly reliable auto-deploy of exploded content 
by using this feature with some good heuristic analysis. Should someone 
contribute to this when JDK7 comes out we could turn auto-deploy back on 
for exploded.
