Specs, anyone?

I suggest a few requirements:

Store the keys, and information about the keys in a *real* database
(for windows apps, we can redistribute the Microsoft access and or
the paradox database engines royalty free, and drive them through 
ODBC to minimize dependency on specific vendors.)

Support tree of authentification:  A key that is *named* Peter by Sam,  
or *named* Informix Corporation by the Delaware corporate registrar, shall
be considered equivalent to any other key given the same name by same
authority, whether that authority be Dark Unicorn, or the state of
Delaware.

This last property is essential if PGP keys are to be used as a
basis for exchanging promises to pay and directives to pay.

A very common use of this feature, pending the development of
user friendly software that makes every man is own bank and his
own credit rating agency, would be as follows:  Sam generates a long
key on a clean off line computer:  He uses it to name itself Sam and to
name several shorter keys "Sam".  He then puts the private long key 
on a floppy disk and buries it in a hole in the ground along with 
his gold and his stash of SKS ammo, and most likely never uses
it again.  He publishes the long public key, and uses
the shorter private keys for actual encryption.  From time to time, 
he changes keys, without any disruption or inconvenience.
