Evan Battle, a Senior Technical Consultant from Pennsylvania posted a script to the NetApp discussion forum a few weeks back, but he figured the VMware Community would be a good place to share it as well. This script query's the VC database for all VM's that reside on a particular data store, takes a VM snapshot, triggers the NetApp snapshot (and retains a user defined number of snaps), then releases the VM snap. The only external requirements for this script are the VCB Framework needs to be installed on the machine it is run from.
