There's a few ways that I've been considering for storing brain related 
information, especially in neurofeedback datasets and MRI datasets and 
the like. The tricky part is extracting value out of it ... as in, 
semantic value, or doing something interesting with data dumped from 
your brain. You could try training artificial neural networks to act 
like small regions of your own functionality :-) which is something 
that Thomas DeMarse has shown relevant technology for.

Hey, want to implement DeMarse's work with Amazon's S3? That would be 
worth a paper or two.

There's a few solutions for this specifically so that there are file 
systems extended across the network, so that cached reads/writes occur 
and so on, but generally there's nothing that is working as well as it 
really should be and you're rightly worried. I know a few individuals 
that I can put you in contact with regarding distributed file systems 
(freenet was at one point somewhat like this). 

http://en.wikipedia.org/wiki/Project_Xanadu <-- pipe dream ;-)

(Also, WikipediaFS is totally worth it ... if it would have directory 
listings ... which by the nature of the mediawiki, it's not quite easy 
to immediately have all of the categories in some giant 
root-node-origin structure .. )
