Fast-transactions and double spending about bitcoin

[gasteve]

I think the conclusion of these discussions is:

1. for smaller transactions, the financial incentive for double spending is not there (the control of a substantial portion of the network needed to pull it out would be expensive to accomplish)
2. for larger transactions, it will likely be permissible to wait for confirmation to finalize the transaction
3. a trusted third party could be employed for instant clearing (payer would have trust, credit or deposit with the 3rd party and payee would trust the 3rd party to not double spend)

I think the problem is either a non issue, or can be adequately solved on top of the current infrastructure (without changing the current infrastructure).
