Yes, that's part of the plan. ;)

Also for recombining I think of the shares being encrypted with the
combiner's public key. In case of an interactive combining process (i.e.
a user sitting there entering a password), encrypting the
secret-sharing's backing store with the combiner's public key would
increase security without increasing overhead on the user interface side.
