I recently read a Goot Trick, might even have been on this list. Bloke 
has software raid configured involving two internal drives and one 
firewire (I expect USB 2 would do as well).

He attaches drive, syncs the RAID, removes it. Takes it away for offsite 

I already new of some of the ideas here:
and my preference is DRBD, but I'd have to redo the research. There's 
also enbd, which requires a kernel patch, but then my research there's 
pretty old too. nbd is in the standard kernel source.
