Actually, you cannot...
eCryptfs, itself, is a stacked filesystem, and it does not stack well
on top of other stacked filesystems (NFS, Samba, AUFS, etc). Tyler
(on CC) can provide more details, if you're interested.
What you can do, however, is use eCryptfs to encrypt all of $HOME or
just $HOME/Private (where you might choose to store your financial
documents but not your photos), and then have U1 sync your underlying
encrypted data, which is symlinked into $HOME/.Private/.
I've heard from several people using U1 in this manner, though I
haven't myself. It's been a really long time since I tried U1 (sadly,
it didn't sync/preserve symlinks last time I played with it and I
think my bug on it was marked won't-fix).
