As I understand it, SRP is an asymmetric protocol, useful for e.g. a client signing up on a website with a password the server will never know, so that the server can verify later that it's the same password as before without actually knowing what the password is.

SMP is symmetric and works only if both parties already know the secret (that's its purpose).

Do you see an obvious way to emulate SMP with SRP? (I haven't seen one.)

SRP requires setup, so I don't think everything you can do with SMP is possible with it.
