Yes.  I think that's me. :)  If necessary, I'll take on the forward port.

"Logical child", in the same way that the hotspot group forests 
(hsx/hotspot-rt,
hsx/hotspot-gc and hsx/hotspot-comp) are children of the hotspot integration
forest hsx/hotspot-main.  Imo, it's up to the component groups whether 
or not
changesets are transplanted as-is from macosx-port to the proposed 
repo.  For
hotspot, we don't intend to do so.  The bsd portion of the port got pushed
recently, and the rest will come along soon, though possibly not in the same
form as Apple's code.

Yes.  Best to start soon. :)
