If it were possible for InSim to send and receive setups, we could not only code up a more automated version of AT's current "send your set for checking" system, but allow a whole raft of other things too. It's not quite as plug-n-play as a server setup option, but it's definitely more flexible. (We could allow ranges of values, we could allow freedom in aspects of setup we don't care about, etc.)
It would probably be less work for Scawen, too.
