As you may have noticed, the homepage of WarMUX has been killed since years. There is no alternative anymore, except on the Internet Archive, perhaps. There is only a project page left. I have no idea why and how this happened.
There is a discussion thread on about the missing home page of WarMUX, which contains some results of my research. If you know anything more about the missing WarMUX page, feel free to post on this forum. :-)
