I'm thinking at minimum a tarball package for ssh-enabled machines to install. Unfortunately I don't think I can really provide a debian package because of the dependency mess.
It also requires a bit of documentation, though a few blogs out there have more or less covered the aspects of gpg keys and duplicity and s3 storage, a 200-line README would be greately appreciated by anybody new to duplicity.
Restore is stupid simple. You just reverse the "source" and "destination" and duplicity knows what to do.
Unfortunately, you need your GPG key to restore, and the documentation needs to make this clear, because the user should know where their GPG key is stored, and to know to keep it secure and recoverable in event of disaster.
Anyway, I'd be happy to make a .BIN package if users weren't such a *****. Though I could build a tarball and a README, anybody interested?

That would let you create a TrueCrypt volume on your backup media and then just use that as the target with any tool.

Reading Package Lists... Done
Building Dependency Tree... Done
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
python: Depends: python2.3 (>= 2.3.4-18) but it is not going to be installed
squeezeboxserver: Depends: sox but it is not going to be installed
Depends: libvorbisenc2 but it is not going to be installed
Depends: libvorbisfile3 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
