I was under the impression that a CA-signed applet wouldn't require
user interaction, but I guess I'm wrong (can others confirm?).  That
does make my solution a little less easy to use for web designers.

Ideally, yes.  But that's beyond the scope of my blog post. :)

Isn't an ActiveX control as easy to install/use as a Java applet?  Or
is it more involved?

I had considered that, though it seemed impractical until you
mentioned Alchemy.  That would be worth looking.  Unfortunately, Adobe
doesn't support it and could make Flash start ignoring it at any time.

That would be good.

This might be worth looking at once Silverlight becomes more
widely-deployed.  I'm guessing it's on less than 80% of Windows
