Customizing Windows 7 with Sysprep in View is the same as Windows XP with the exception of having to put the Sysprep files on the VC server.
Simply create a customization specification in VC and then select that when creating the pool. This will call Sysprep when a desktop is deployed and the SID will change. If you fill in the domain join settings it will also join the domain.
If this isn't working I would suggest filing an SR to have it looked at. You can also try this through VC first without View (using the deploy from template option) to see if it will work there.
If you have more questions let me know!
