How can I have an encrypted Time Machine backup on my Time Capsule?
The option is in Time Machine preferences, but greyed out. Anyone know of hacks/workarounds to make this work?

This gentleman describes the process in full and he knows what he's talking about.
He uses a Time Capsule and 2 MacBook Airs for his setup.
Encryption can only be done on a directly connected drive via USB, Firewire, or Thunderbolt port. Wireless drives, such as time capsule, are not supported for encryption.
