As I write this, FireDrop is
revealing their product, after over a year of extreme stealth mode
(during which they "filed dozens of patents" -- terrific). It's called
Zaplet. It's a "convergence of the web, email, and instant messaging"
also used: "live, shared, smart email." It seems like HTML mail, but I
don't fully understand it yet. I think I'll go to their presentation
this afternoon (this was just an introduction).
