You can contact two peers and middleman between\nthem to produce a single tx.\n\nThe practical problem with a signalling tx is that it's hard to tell if\nit's conflicting.  Mallory uses a single UTXO to probe for everyone's\nUTXO at once.  Poor Bob wants to both wait 60 seconds to see if a\nconflicting tx ends up in his mempool, *and* broadcast it ASAP to signal\nto others.  He wants to do both of these *before* revealing his own\nUTXOs.\n\nNot sure how to square this, but I do prefer this approach over PoDLE.\n\nCheers,\nRusty."}
