I have a need to find a Contacts/Address-book/or integrated mail application that permits the lockdown of the contacts data. Ideally, the info stashed in that Contacts application would be password-protected, encrypted, and could be written directly to a removable device location - in other words, ability to change the default destination for the store to a USB or otherwise removable "drive".
Anyone know of such, or know if there is a version of Outlook or Thunderbird or ???xyz that would have such features configurable?
