Suppose Jesse sends me his key via e-mail.  Once I've signed it, 
is it correct that I need to export it using the --armor option 
and mail it back to him?  

Some people don't want their public keys on keyservers, so I
assume it would be very wrong for *me* to send the key to
pgp.mit.edu, if Jesse hasn't already put it there himself,
no?  

If Jesse keeps the public key, signed with many signatures,
essentially private, releasing it only upon request, what is
the value of the signatures?
