Huge +1 to this. One of the dangers in this multi-signatures area is
misinterpretation of what the signatures really mean.

There are many possibilities here that are neat cryptographic tricks
that are in search of a use case. As Joe states, we need to be very
careful that the interpretation of these multiple signatures are not
interpreted to mean something the signers never intended.
