Yes, Apple thought of it years ago. Plug a Mac/laptop to another Mac via 
Firewire (and I think USB too), boot it while holding down the T key 
(I'm pretty sure it's T), and it boots as a slave drive.

This was a standard feature used when you upgraded hardware and wanted 
to migrate your data across. Not sure if it works on Intel Macs, but 
don't see why it wouldn't.

However, this feature also relied on the BIOS. PCs don't have this. And 
if you just plugged two PCs together via USB, each end would be 
connected to a motherboard, or a PCI host card, not an actual device.

I have never seen this done in PC land, and it would probably require 
hardware/BIOS changes before someone implemented this in Linux.
