Re: comments on client auth

I'm always glad to hear that; I consider it a major part of my job, regardless
of who I work for(Not that I take pride in it necessarily:  I've found
that any idiot thing can cause me to think about completely unrelated things).

Doubtless.  That's where my money is invested for now...

If anyone was in doubt about that, I apologise for assuming it.  It may
be that they were.  It may also be that they felt that the mere
possibility of securing machines against tampering with root keys
solved the problem of being sure that it was so.  As an implementor I
have wrestled long with this problem.

I don't think I follow here - isn't the idea to resolve the names by following
the references to their sources, thus making comparison possible?
