Those of you who went to the RSA show in April and who visited the RSA booth may have seen a proof of concept showing an integration between VMware vShield Zones and RSA's DLP product. It showed how these products working together can prevent leakage of sensitive data in email, web traffic, etc., right from within the fabric of the virtualization layer itself.  There is now a video posted which was taken during the show and has VMware's Allwyn Sequeira and RSA's Magnus Nystrom going over the demo.
