Dealing with encode and decode are two distinct problems.

I thought a bit more about sign/encrypt after I sent that message yesterday, 
and it seems that it should be possible to put together a script that can be 
invoked at the what now prompt to handle the PGP (or S/MIME) 
signature/encryption steps, and do the required MIME massaging of the message.  
This is how (al)pine handles PGP.

The receive side is a bit trickier.  When a multipart/encrypted is spotted, we 
need to loop that part out to an external process that would handle the 
decryption and return the underlying content.

As long as we can dispatch based on the 'protocol' parameter, MH itself can 
remain completely agnostic with respect to the encryption method.  I'm pretty 
sure we have all the logic required to specify this, so the real work is in 
adding the code to pipe the multipart/encrypted part through the external 
process and insert the decoded result.
