Distributed Switch across datacenters and clusters..

Hi

can a vDS be distributed across hosts in different clusters and/or different datacenters (in vCenter)

2 datacenters in London (physical) with hosts in each.  Each has a couple of clusters for prod, DR..  can a vDS for Prod and a vDS for DR be stretched across the 2 DC's?  i understand that there will be physical networking aspects to consider but i would like to understand if vDS can ultimately do this

thanks in advance
