Looks like the comments showed up - summary:

1. The changes were smoothly applied, did not see any major workarounds like in GeoTools or uDig
   2 We could make use of some of those DataUtilities methods.
2. I tend to do try / finally around each FeatureIterator
3. The security feature collections were fine, I wanted to make sure there was no way to accidentally get to the delegate and "add" anything. And yes they are all wrapped up
