A Japanese software developer was arrested recently because he
developed a P2P file-sharing implementation called Winny. Winny can
be used legally, but some (well, I should say many) people used Winny
as a mean of copyright violation (file sharing of proprietary movies,
music, and so on). And somehow the police arrested those violators as
well as the developer.
See:

So, at least in Japan, I think it can be dangerous to develop or
distribute legal tools with some foreseen illegal use. I know it's
almost insane(we Debian already distribute such software), and the
trial is not yet concluded, but that's the situation nowadays.
As usual, IANAL, btw.
