Faronics Deepfreeze & Symantec CMS patching

Is anyone out there trying to push patches to machines with deepfreeze on them, especially laptops?

I can't think of a good way to do this because our machines will go to sleep before patches have a chance to install (if we set up a DF maintenance period for patching).

I see Faronics has their own Core solution for pushing updates, but it looks like it relies on WSUS - it would be disappointing to have to manage a WSUS on top of what we do already with CMS.
