I think the way to do it would actually be best as a total of 2GB  
mounted, using software RAID-5 to write everything in multiple places  
(I don't trust MMC cards for long-term storage any more than I trust  
floppy disks.  Well, ok maybe a tiny bit more, but not a lot).  I  
would use the network block device system (nbd) to export the 6 MMC  
cards to the LAN, then attach them as block devices on the frontend  
machine.  Then do RAID on the client over the 6 nbd's

It looks like I'm having trouble accessing the author's site right  
now, but google has it cached:

Looks like from that page and Documentation/nbd.txt in the linux  
source tree, we'll need to get the nbd-client and nbd-server  
userspace apps in the buildroot.
