Here's a fascinating link to Daily Pundit via Insty with pics of his Blogger Reporter Kit. Its a bit expensive for me at 1700$, but I could see giving this set-up to one of my characters in Codeword: Anoniblogger.
And, mmm, a felicitous spelling error makes me wonder Codeworld or Codeword? Which is better? World does speak to the idea of a worldwide net of secrecy; word sounds like something out of a spy novel, and that may be good, or it may be cheesy.
