Thanks Hal! @p{par}

If I had a cluster of bitcoin transaction processing nodes (or a big mining farm), I'd connect them with memcache and store transaction hashes/verified flag pairs, so signatures were verified once.  Or maybe just have one machine filter transaction/block traffic and only pass along valid transactions/blocks, and not have the rest of the machines even bother checking signatures. @p{par}

It will be tougher for individual nodes.  If they're not mining, they could just check signatures ONLY on somebody-sent-to-them transactions.   @p{par}

If they are mining... well, it seems to me  single-node miners will become increasingly rare as bitcoin scales up.  Hardware farms or miners using a mining pool seem like the way of the future. @p{brk}
