Bah, I don't think there are that many users of the technique yet, and they probably are all in the recipients of that mail, or at one hop ;) In any case, this is very exciting stuff, be quick, I'm doing a talk at FOSDEM (Feb 23-24) and I'd _LOVE_ being able to demonstrate such nifty tools ! -- ·O· Pierre Habouzit ··O [EMAIL PROTECTED] OOO http://www.madism.org
