If you see that great a loss of data I suspect no distributed scheme is
going to be completely unaffected.
The thing about FreeNet is that a lot of the questions you raise have
already been mostly solved.
The big downside to FreeNet in particular is that it is already contains
the kind of data that will get you arrested and prosecuted for kiddie pron
if you run it and get caught with it on your PC.
I've been looking into properly distributed data with decent indexing for
a while now and it's not fast - in fact everything I've seen trying to do
this so far has been slower than I think most users would consider
reasonable. That's one of the reasons my distributed contact system idea
never went anywhere.
