I wonder how bitcoin would handle it growth?
I spent ~6 hours downloading all blocks. It also took almost 200Mb on disk. I wonder what would happen if bitcoins would be used 100 times more than now. Will it take 600 hours to download blocks for new clients and will it use 20Gb then?

I bet AMD would be very happy to sell their cards to all sides of the battle in unlimited quantities . And except of dozens of cards you will need MBs, RAM, CPU, really lot of power (up to dedicated HVAC line), really decent cooling (and it's very expensive) and actually this will be one of the a best supercomputers ever. And overall installation would be fairly expensive, maybe several hundreds of M$ or even more. I doubt bitcoin makes someone lose so many money so it would be a negative profit. Except for AMD who would report a really good quarter  .

P.S. maybe I can have unban? Actually I want to thank Con for his miner, ask question about cgminer and damned AMD/ATI bugz  and report couple of bugs/annoyances into cgminer thread since I spent 2 days hunting bugs without success. So I have a question about all those AMD things vs miner program.
