Nice link.  I am already a squatter.  Discovered the benefits of it when travelling in India & Burma.  Of course, its outhouses or open woods where I live now (rural Appalachia), so it's easy.  I hate using the conventional western setup.  Yours is a snazzy device indeed.

A friend of mine was staying in rural Japan in the 1960's.  After a few months he was very tired of squatters and became homesick for Western porcelein.  His polite hosts told him about a Western toilet that had recently been installed nearby.  He was very keen to try it out.  So, when it was time, he eagerly sought it out only to find that it had been installed backwards.  The lid opened towards the wall and it was tight up against the wall.  He just laughed and used it by squatting on the seat facing out over the tank, just like everyone else had.

Peace,  Zapple.
