Sure, I (perhaps with Keshav as a backup --- Keshav, would you mind helping?) can do the admin. I suppose 10 hours is still acceptable for a build (I expect it actually be quicker with a HD, as the solid state drive in my AC100 is kind of slow, and might take a lot of wallclock time during the build). I certainly cannot predict how often a manual intervention will be needed, but let's hope for the best.
