Update: So we just happened to have a Thunderbolt on hand, and gave Skype's mobile video chat a try. We came away quite impressed -- video is as good as can be expected from the handset's 1.3 megapixel front-facing camera, and the experience on WiFi and LTE is virtually indistinguishable. The app even worked on 3G, though that reduced the picture quality to the point of being almost unusable.
