Shared storage in VMware workstation

I'm playing with VMware ESXi and one of the features is migrating between hosts that are sharing storage. Obviously I don't have two SANs in my flat, but you can achieve it with VMware workstation for testing purposes by editing the vmx files after creating the storage:

Create an independent, persistent drive as a single file.

shut down your hosts / VMware workstation and edit the appropriate vmx file for each host, here are examples to work from:

# Amend, change these:
scsi1.present = "TRUE"
scsi1.virtualDev = "lsilogic"

scsi1:1.present = "TRUE" 
scsi1:1.fileName = "E:\vmware\sharedds\sharedds1.vmdk" 
scsi1:1.mode = "independent-persistent" 

# Add these:
disk.locking = "false" 
diskLib.dataCacheMaxSize = "0"

Do this on both (or more!) hosts vmx file and you should be able to boot them without locking issues.
