I found the beta on usenet. It was in the newsgroup
alt.binaries.quebeq.hackers
or
alt.binaries.quebeq-hackers
something like that. It is in the top 10 newsgroups with the most articles so it shouldn't be hard to find.
It was there two days ago. I don't know about today. I am pretty sure that I spelled quebeq wrong and don't feel like googling it.
I dl a beta like 6 months ago from usenet (not the same newsgroup) and the file was corrupted. So no guarantees.
