I would like to know whether those "alternative arrangements" for delayed payments violate the terms of the motion in any way? If so, I am definitely against those alternative arrangements. We should stick to the motion, no matter what.
The motion is quite clear and I don't see room for alternative arrangements.
All BKS that have not been purchased before 2015-08-21 23:59 UTC need to be burned at 2015-08-28 23:59 UTC.
Who purchased before 2015-08-21 23:59 UTC needs to have deposited the payment before 2015-09-04 23:59 UTC.
The only alternative arrangement I can think of is a payment very close to 2015-09-04 23:59 UTC where the transaction is on the network, but not being processed fast enough to reach BCE before 2015-09-04 23:59 UTC.
I can imagine to save those BKS from being destroyed and wait until after the funds have reached BCE.
The BKS from people who purchased shares before the blockchain was created need to be excluded from the burned BKS. They will be delivered as soon as they provide BCE with a BKS address to deliver them to.
I assume that payment for those shares has already been received by BCE. If not, the motion applies to them as well.
