But there's another issue: if we throw away the SK that we used to
sign the fragments after we generate them, then a lost fragment is
lost forever. There is no way to 'regenerate' fragments that have
been lost. This means that documents will get more fragile as time
wears on. Which means we *must* use some sort of active checking
system (which can regenerate a lost copy since it still has an identical
copy) like the buddy system that Ron proposed.
