When considering these costs, using a normal P2SH output + a script with OP_IF and friends seems more straightforward? Doing boolean logic with multisig groups is quite possible, e.g. "group AND group", "group OR (group AND group)" etc. Definitely a valid use case. I discussed how to do this on IRC with gmaxwell several months ago. I call it "multi-multisig" for lack of a better name. ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
