Nice setup. I had to try this and it's working here:

sid0# sshfs root@localhost:/mnt/disk/enc /mnt/disk/sshfs
root@localhost's password:

sid0# mount -t ecryptfs /mnt/disk/sshfs /mnt/disk/dec
Attempting to mount with the following options:
  ecryptfs_unlink_sigs
  ecryptfs_fnek_sig=14f4412383d9220f
  ecryptfs_key_bytes=16
  ecryptfs_cipher=aes
  ecryptfs_sig=14f4412383d9220f
Mounted eCryptfs

sid0# cd /mnt/disk/dec
sid0# cp -a lib/dpkg/ bak
sid0# diff -r lib/dpkg/ bak/


sid0# uname -a
Linux sid0 3.8-trunk-amd64 #1 SMP Debian 3.8-1~experimental.1 x86_64 GNU/Linux

sid0# dpkg -l | egrep 'ecryptfs|sshfs' | cut -c-80
ii  ecryptfs-utils                             103-2
ii  libecryptfs0                               103-2
ii  sshfs                                      2.4-1

Only extended attributes do not seem to be supported. What versions are 
you on? Does strace(1) reveal something useful?

Christian.
