1)   If I use a removable disk storage tool (like pen drive) and the
computer of the downloading is virus infected do i have the risk to
damage other machines?.
2)   And if Google manages to have series of authors that are agree to
divulgate their books for a truly average earning based on hits of the
people can we overpass the old and not useful for development rule of
70 years before expiring of author right? Anyway watching a book from
the screen at the moment is still less  valuable than to have paper
copy....
3) Last of all, does the price of the paper can be not variable in the
last 50 years dues to artificial way to produce paper than can
increase supply for the other way to transmit culture?
