This sounds like a fun feature!

From Joi Ito's Web: Will airtexting BlackBerry become the mobile hecklebot?:

QUOTE

If they made an airtexting enabled BlackBerry, I wonder if they would allow them in Congress. With the massive penetration of BlackBerries (NYT - A BlackBerry Throbs, and a Wonk Has a Date), it would be like a chorus of Hecklebots. Anyway, I want one. Forget night clubs, imaging having one in the audience during talks.
