ok, I will try to understand... but what will happen to micro transactions?
Despite the information disseminated by some rather vocal supporters Bitcoin was never designed for doing transactions that are so ridiculously low (you may have noticed that Satoshi Dice has copped a lot of flack for the way that they send back *dust* to let a player know that they *lost*).
For truly tiny transactions "off the block" methods are likely to be the only reasonable method (I don't think that most people running a "full client" want their hard drive to filled with 1 Satoshi dust transactions).
Of course if 1 BTC becomes worth much, much more then maybe even 1 Satoshi tx's may make sense but I don't see that is the case now.
