I'm not using EFS yet, but am considering it for some folders.

This example makes me wonder ... here, people continuing logging in to 
the domain on off-site laptops (using cached credentials, I think you 
call it). Generally the only local account is administrator and they 
don't even know the password.  Would EFS continue working off-site?

I would think the EFS key chain would also be cached on the laptop.

And am I missing something by not using local accounts on the laptop?  
My research led me to believe everything should be done from domain 
accounts, and the local accounts secured at installation and basically 
ignored afterwards.
