The whole thing is far from final shape.  :)

The issue is that we have two, not that it's there.

I didn't take it that way.  Just iterating my "lowering of expectations" :)

I agree that later we should, but in these first iterations as we get
our act together, I figured that including useful things for people
would be good.

We could just call it the JDK rather than JRE, but that just brings up a
 bunch of other issues that I'm not sure it's worth slowing down for.
Maybe throw it in a directory called "goodies" or such, so it's clear
that it's something odd, and put a note in there telling people what to
do with it?
