I think it is a reasonable assumption that major miners will be well-connected with each other.  There is certainly a strong incentive for miners to be well-connected in general (better connected == more likely to win 'block races'). @p{par}

So I don't see how you could freeze the block chain@p{--} if you generate lots of double-spends, the miners will quickly see both of spends and will drop those transactions like hot potatoes.  The "finney attack" only works if the first double-spend is generated by a miner that finds a block and includes it in the block without transmitting it. @p{par}

Also, my proposal was to only reject blocks containing 'suspicious' transactions that you hadn't seen transmitted that have a double-spend attempt before the next block. @p{brk}
