let me begin by saying that i have tried this in the past. when the
number of messages involved that are treated this way is small, i
agree that it is actually not such a bad idea. btw, i agree w/ you
about the "deep interconnection" -- i do not worry about that ;-)
when the number of messages that you deal w/ grows, then i submit that
it is not a practical solution. it certainly doesn't work well for me
right now -- months after i have sent or received certain messages w/
cryptic subject lines.

yes, i could do this -- this solution and the one you mentioned above
are practical in the situation where the number of such messages
when the number of such messages grows and the time since reception or
sending of message grows to a certain length, it is not very
if there is no method of dealing w/ this intelligently, i think some
mechanism should be designed.
i would like to hear the opinions of other users of gnupg/pgp as well.
