I like the idea of the "surrender button" provided it has enough safeguards to prevent accidental triggering. It would have to be limited to GL of the attacking or defending guild. (Your GL can't make it? Have her appoint one of the HOs as temporary GL. If you can't count on the HO to hand it back, then he shouldn't be an HO.)
