Spamming the block chain

[cloudswrest]

It would seem to me that one way of reducing block chain spam is to enforce a minimum transaction amount (not resolution), and/or a maximum transaction size (unless extra fees are paid). Since bitcoin has a built-in measure of it's own value in the form of average transaction fees people are willing to pay, this minimum amount could be dynamically adjusted similarly to the way the "difficulty" is adjusted.  This measure of it's own value could also be used in calibrating what is and is not "bit dust" for any future consolidation.
