various spellchecking/rewording

Some notes:

Reword the conditions on lines 43-44, and lines 63-64.

Explain where the value "7" comes from on line 97.

Explain the distribution attack. Why is it a problem that attackers can affect the distribution? What "direction" would they want to push the distribution in?

Explain the voting system: do hosts receives votes proportional the amount of files they store?

This paper talks almost entirely about files, not data. Are there protections against one host storing 10 10KB files, and another storing 10 10GB files?

I only edited up to around line 97. The rest of that section needs a good deal of clarification.
Anyway, going from standard deviation to price shouldn't be so bad.

If a standard deviation is 10 (meaning 100 files per host), half would be 5, meaning you have to pay for the favorable reorganization of 5 files when you quit early. So your down payment would need to be 5% of all income that you'd make throughout the duration of your preallocated stay on the network.

This same sort of logic can probably be applied to 'losing' files too. We can probably skip the dirty math and just assume that if you lose a file, it's because you've intentionally tried to reorganize it. This means that we can also allow you to selectively lose files, at great cost to yourself.

Perhaps, to defend the honest hosts, we have a different penalty if you just wholesale lose all of the files. Because if you lose all of the files, we can assume that at least some of them are honest. But at the same time, if you're maliciously losing a whole set of files, it's probably a set where you wanted to move a majority of the files.

=/ darn. Not simple math.
