In Germany you, as the owner of a internet access point, are liable for whatever some person does with this line.

It is called 'Störerhaftung'. That way it doesn't matter who exactly did illegal you download stuff. You are liable non the less.

Funny thing though - the moment you are an incorporated ISP you do not fall under this concept anymore.

That is by the way the reason free WiFi isn't that available in Germany.
