Not much to add to the S/MIME part: while email clients are generally 
rather user-friendly, the casual user will get lost as soon as you 
mention "X.509", "public key" or "private key". And managing CRL's is 
no piece of cake either.

Often you'll need one more thing: the ability for management to recover 
the plaintext of an encrypted message. Key escrow, in a word. I don't 
want to start an argument about whether it's a good idea or not, but 
face it, it's a requirement in most medium to large companies.
