Hmm, perhaps we should make a reference to CFS/PAST in this specific part: If
these system somehow differs, we should explain how. If not, tell that 'they are
very similar etc'.

Btw, how Storm blocks are shared among computers ? Is it more like CFS or
PAST(CFS: files are splitted to blocks (merkle-style), PAST: share whole files)
? Or is Storm more like decentralized index, which has 'pointer references' to
blocks: find computer which points to another computer, which hosts the actual
block ( first block would be a dummy block, e.g. record of hash and ip 
address.) ?
