The answer to (3) directly is, "no"* - which is why SPF is so useful, 
since it doesn't require large (or any) changes to a user's clients 
(assuming you're not doing mailing list expansion via your MUA, which I 
believe some packages do).

The SPF pages at pobox have all the details you could want, including 
pointers to various implementations. It's pretty simple and 
straightforward; furthermore, the license situation is positive. If the 
MARID stuff ends up encumbered with what RMS calls a 
non-free-software-compatible license then it's quite likely that it 
simply won't fly, regardless. SPF itself is in use right now, however.
