This strikes me as extremely ambitious - so much so that I doubt it will
be fully implemented in the near future. A useful subset of it might be
implemented, though.

I don't think that trying to do any useful manipulations on encrypted data
(section 4.4.2) will work in practice; appending an update log and then
occasionally consolidating and re-encrypting the object should work, though.

Note the *big* assumption that faults are uncorrelated in the analysis
in section 4.5. I'm not sure this is reasonable even in the absence of
deliberate attacks.
