This question has been raised a few times lately, and I thought I would try to give the answer a little broader distribution.
Yes, as of vSphere 4.1 Update 1, we have included VMware Data Recovery (vDR) with the Standard product edition, which means all of the editions now include vDR. You can see more detail here.
What is not in that nice chart is that if your subscription is current, people that bought Standard before Update 1 also are able to download vDR and use it without additional purchase. This is only true if they have maintained their subscription which is most generally true.
vDR is a great product and I am glad more of our customers get to use it now!
