OK, I did get a reply just now from anonymous via e-mail stating the following, to quote:
"sorry for late response... been working alot. i am currently checking for riv pub priv ctype. currently doesnt appear that lv0 hosts those keys however lv1 seems to host most of them. after some verif ill email you my results.
So I guess we will await further word... at least we got a reply I suppose vs none at all.
