When a rare directory namespace collision ten years ago made us aware of each other working at the same company at the same time, I discovered that I have an homonym. He lives in Auvergne and that is about all that I know about him apart that I suspect he is much older than me. Maybe I should call him some day.

Later I discovered that there is another one who lives in Switzerland. Are there that many Liotier ? Meanwhile you know who the real Jean-Marc Liotier is – beware of imitations !
