+1 (binding)
We have made some great progress in the last few days on some of the issues I 
raised.
I have posted a summary of the followup items that are needed on the Jira today.
I am +1ing expecting the team will  complete Items 1 (distcp/cp) and 2 
(webhdfs)  promptly. Before we publish transparent encryption in a 2.x release 
for pubic consumption, let us at least complete item 1 (ie distcp and cp) and 
the flag to turn this feature on/of.

This is a great work; thanks team for contributing this important feature.
