Impact of Netscape kernel hole

[nobody@huge.cajones.com (Huge Cajones Remailer)]

It'd be nice to have more specifics about the whole situation, but
regardless - any preliminary threat assessments?  Exactly how widely
exploited do you think this has been?

Tim's post (although refuted by Marc) raises some serious issues since I
suspect that Joe Public has his secret key sitting in c:\pgp\secring.pgp

Some coherent input on the possible impact of this would be appreciated.
