Heh, check this out:

Sorry Perry, I had completely forgotten about all that stuff.  Now that
you mention it, I do remember your install stuff, it was very cool.
But I'm horrible with names, when I was teaching at Stanford I'd have
students come up to me from a couple of semesters ago and I'd have no
idea what their names were.  Sorry about that.

Well welcome to the old farts club, I'll cut you some slack :)
I still think you are missing the point I was trying to make,
it's amusing, a bit, that you are preaching what you are to me
as a guy who moved Sun in that direction.  I'm not at all against
your arguments, I was just making a different point.
