Chasing yourself now, Casascius?
I hope Mike wins the bar
That would be ironic
Maybe I'll put in multiple orders to increase my chances of getting the bar, damn how are you guys doing the group buy going to handle that!
I don't see a problem with the draw and group buy?
If the books are serial numbered then will the draw speak for it self. If the draw is order based, then will the group buy organizer just make a local draw between the buyers. If you trust the group buyer with your bitcoins, then surely can you also trust him to make a fair draw. You can even have a trusted 3rd party to do the draw, but that would hardly be necessary with Mitchell or MJ as organizers.
I think it is by book number, maybe it didn't specify
Also something about a provably fair seed
but either way I think this will be pretty simple
