Either way it's a two-step process: "git pull; git remote import" vs. "git pull; ./import-remotes.sh".

I actually don't care to limit what the clones can see. I understand the reasoning behind such control, but in my case it just doesn't apply.

Point taken, but I think I will start with no origin-side controls, since I have no need for them anyway. If/when I cobble together a patch hopefully at that point we'll be able to have a wider discussion about such controls.

Many thanks for taking the time to discuss this. Now I've got to roll up my sleeves!

(BTW, any pointers to descriptions or overviews of git's code base?)
