I suggest using a dictionary to come up with "names" of anonymous users: aback abacus abalone abandon abase abash abate abater abbas ... You could pick them in random order, or sequentially.
Suppose the ante goes up and all this stuff becomes actively illegal. What then? If a large network is *already* in place, the risk is much lower than trying to do something after the fact. And it would be a more mature network
This technology is sufficiently cheap to replicate that it doesn't matter whether we set up a "covert" network before or after it becomes illegal (if ever). What matters is that we have experience at running such a network. Such experience is much easier to come by in the open -- since you can talk about it! While I applaud the efforts of some people to set up contingencies for "after we lose our liberties and need to actively oppose the government", please don't forget to actively oppose poor government policies *now*, before the loss of that liberty. In other words, there's plenty of work to be done today to *keep* this an open society. And it's much easier to keep one than to get one back. John Gilmore
