Indeed. Too many distracting projects... But I was just going back to it, honest!

An enhancement I'm making (which I'll post once I've got it working; you may want to incorporate it, or not) allows easy swapping out of the relevant files in /etc for boot/chroot usage.

I'm actually gonna grab your .deb, rip its guts out and spill them all over my computer, and try to put together a reasonable hybrid. I'm liking the xephyrized method you've got going, at least as something to try. Besides, I don't feel like copy/pasting out of the wiki for all the scripts. So, tomorrow, maybe, I'll have some answers.
