I'm disappointed that no one is taking this opportunity to discuss solutions to spam attacks (dust transactions w/ maximum outputs). That's actually the issue that is forcing this debate -- not organic growth in transaction volume, which on average, is nowhere near the limit.
I'll admit that I'm not entirely familiar with the issue. Can you give an example?
I thought there is a dust limit of 5500 Satoshis. is that set by the miners by consensus or is part of the protocol?
