Yes, I've tested this appliance awhile back while it was still in beta prior to vSphere 4.1
Please take a look at the VMware Lab Flings documentation for Autodeploy, all the instructions needed to get setup is there: - http://labs.vmware.com/flings/vmware-auto-deploy
Also note, you need host profiles feature to customize your ESX(i) configurations which in-turn require either an evaluation license or Enterprise Plus
