I have not tried, but I, too, am excited at the prospect of giving this a whirl. I would think that once bead is broken, you may be able to fish straps around a flatted tire and do same in reverse. May not be faster than using tire irons, but could offern an option. Still, which is more of a pain to lug around, 3 tire irons or 8 straps?
Tie wraps could work, too. They would only have to hold the tire pinched, not necessarily pull it closed (you could stand on it, etc.)
I will mention it here, as it falls into the same "crafty/McGuyver/outsidethebox" mindset--Someone here mentioned breaking the bead of a flatted tire loose with another bike's sidestand. Both of these tricks may save me considerable grief in the future.
