"On further reflection though, this may allow groups of gridders to more effectively use strategic reservations, and simply expire them when they know their partner in crime is ready for it. I'm not sure that is a good tool to give to the more nefarious players."

yeah, sadly, i think anything that can be exploited in such a scenario will. but more than that, i tend to stick with the philosophy that SNY (and others, as i recall) made reference to earlier: namely, the grid has worked this way (the way it is now) for a while, and will likely keep going.

ultimately, however, my secret is that *laziness* and *overextendedness* will likely keep me from making this change; so no worries. besides, folks are pretty tolerant of when this happens accidently.
