Bootable backup over the network?

[awm]

I just downloaded SD today for evaluation, and was hoping to be able to create a bootable copy via the network (planning to get an AE base station soon).

I planned to create the inital backup to a locally attached USB drive, then hook that drive to the network for incremental updates.
After coming across this post, I sadly realize this probably won't work, even with HFS+/Journaled formatted drives and over AFP (right?).

May I suggest a feature then (couldn't find anything like that in the docs or in the forum): How about the ability to create a bootable mini system on the same drive that's able to (1) boot the Mac when plugged in directly, (2) mount the image and (3) restore all the files?

I realize this could probably be done via booting from the original CD/DVD, but I find that procedure highly annoying (esp. searching for those CDs/DVDs).
