Oh...and then we get into P2P distribution mechanisms. How is any
ISP supposed to block content which is everywhere and nowhere?
This would only be possible by whitelisting content, which is not what
most would accept. (although there are countries where this is the norm,
but their citizens are not exactly happy with the norm either)
With technologies which do pseudonymous random routing over tunnel
broker service, applet brought to you similarly to Flash or Shockwave
"plugin", intrusive technologies become even harder to implement
reliably. And it's probably the older kids who use this technology
before the ISP or the parents. The numbers are still in thousands, but
in the P2P world, going from minority to majority is 12 to 18 months.
