Agree but if you let them first work with a testing keypair they can get
familiar with the wholestuff without too much of damage.

Agree again but most ppl are not even able to remember a single
passphrase, with 2 of them it will be even harder.=20

If then one could add the complete functionality of a GPL=B4ed GPGShell =
GPGRelay it would be a great step ahead.

yep, still my auto-key-retrieve produces eof-errors all the time

That sounds like the solution for all of our problems :))

AFAIK this all is intended to secure the way to a reciever, not to
secure the reciever ?

Again, with GnuPG one can do everything that is needed to keep things
secure within his own Sphere of influence. If others do not share our
thoughts on security risks we can not blame them for that but if risks
come true at least they can not blame us.=20
