I've heard of it, tried to find it, it appears it's terribly unstable, doesnt support everything, and I think it may even be postponeded or discontinued, you do realize if it becomes a sucess, it'll hurt their C# release(which I think it stupid anyways) and It'll hurt the fact that people will use Netscape instead of IE, I am sure that Microsoft has some kind of patent that only allows Microsoft browsers, or microsoft development tools to decode ActiveX controls. Or something like that.

My boss was asking the same thing, he even wanted me to find out if I could embed an ActiveX into a Java applet (hehe)
