I got my false impression from the following sentence in
"Therefore only the simultaneous failure of N-K+1 (with the defaults, 8)
servers can make the data unavailable."

As a Tahoe-LAFS novice, I agree completely. So if I understand
David-Sarah correctly and in the default configuration only 4 out of 10
servers can fail without bad consequences for my data, my logo is
completely misleading and shouldn't be used.
So what would be the best way to learn about the exact meaning of those
shares.total, shares.happy, shares.needed parameters, and how shares
relate to servers? I've started reading ticket #1092, but that seems to
confuse me even more...
I guess I'm looking for some kind of glossary for Tahoe-LAFS that
defines the basic terms and their relationships. If that doesn't exist
yet, I would be willing to help creating one. Well, all I could do at my
basic level of knowledge would be to extract text from the existing
docs, and let someone competent proof-read and correct it. But maybe
that's helpful nevertheless.
In the end, something like the "Visual guide to Chef" for Tahoe-LAFS
would be brilliant: http://www.mynameiskate.com/visual-guide-to-chef/
