The Ethermedia page doesn't exist, and it seems that the project is dead now.
escargo - Checking out the site using the Internet Archive found a copy of the subject page from 2006: https://web.archive.org/web/20060514043422/http://www.ethermedia.jp/
There were a couple of later copies in the archive, but nothing substantive in them.
