Without re-encrypting that data, the only thing "protecting" it are
filesystem privileges, and those are trivial to bypass.

But it can encrypt as it writes. That's what happens when I write anything in my FileVaulted account, right? It is on-the-fly encryption and decryption. If it can do that for everything I do as a logged-in user when writing to my hard drive, why can't it do it for TM writing to an image?

I still think that this is just a glitch that Apple is going to work out. Unless there's something fundamentally different about writing to an image than to a physical disk that I am just not understanding.
