My Facetime suddenly started working. I did the 755 boot file, edited hosts file, and all the normal stuff, and none of that "seemed" to work. I tried one last thing, that possibly made it work? I had my time zone set to GMT and internet updating of date and time OFF (as I have a Win7 OS on another drive in my desktop, and got sick of resetting the time over and over again) I enabled internet time updates, and set my time zone to where I am actually located, and upon next reboot, it started working. Go figure. I am also following another member's suggestion to never quitting Facetime, even when shutting down Lion, and that seems to be good advice so far...
