I think the benefits are several-fold - instruct me if you differ, please:

1) cheaper to retrofit to existing hardware

2) cheaper to implement on new hardware with low-cost or free VM
software, like Xen (or QEMU on *nix boxen)

3) achieve benefits of both file/directory encryption and whole-disk encryption


It does cost some user annoyance with having to sign in, launch the VM
and then sign in again, but it might well be worth it for the benefits
involved.
