Well, good news/bad news:
First the good, it is working again. The bad, I don't know why. I unplugged the OBi110 and got sidetracked while testing calls from the gmail chat plug-in. When I plugged the Obi back in after an hour or two, everything worked. The extended disconnect must have allowed a connection to clear somewhere between Obi and google. Short power cycles, reboots and reconfigurations didn't work earlier in the day.
Also, the mobile client and 2 step calls using my cell phone from the GV page worked throughout the outage.
As for the google apps and private email thing. I highly recommend it. It's basically a free service that lets you host your domain on google. You get web based gmail for your own addresses. Lots of other features as well. They handle annual domain registration, so you pay google instead of directly to some of the less desirable registrars! search "google apps."
