I would love to see mailers (anyone from Qualcomm or Netscape listening?)
keep mail archives enciphered under one or more storage keys. Symmetric
crypto is fine for that. PGP mail can have the signature left attached to
the cleartext (all enciphered under the storage key).
This would not only keep my aggregation of data private and useless to a
thief, but would separate the two issues.
