Thank you for not mentioning the outside world

Is there a proxy that would let me filter any content with the words “SXSW” or “ETech”? That would help me feel a bit better about being in Michigan over the next week. I suspect the Chinese have it in place to keep all their geeks from spending this week in the US. Maybe there’s something to auto-block people who use those words in IM, or I could install something like netnanny and tell it that those are swear words. Not that I’m bitter…
