Looks serious.
It seems as though the domain name has expired and has become available again (I think - but my Euro is poor) If so, then I doubt very strongly indeed that it will be back at all, as the project was completed some time ago.
It does appear that Project Zeta has finally tasted dust.
I wonder if JimB0Th can confirm this for us. I have posted in his forum. Perhaps he can obtain some confirmation through his contacts.
In the mean time, as I assume that this is the end of "lots of nothings"thanks to all of you who gave it a go, threw down gauntlets, picked up places and otherwise gave us challenge.
Vive le Zeta long temps.
