We just dropped by Contour's booth at CES to check out the new Cerevo Live Shell accessory — it's a small, light, portable device that can hook up to an HD camera via HDMI and stream live video to Ustream over ethernet or WiFi. Settings for the Live Shell can be managed on a PC or through a smartphone app, and when paired with the Contour+, the system can capture roughly three hours of 1080p video on three AA batteries. Contour had a live demonstration at its booth which looked pretty smooth — video streamed from the Contour+ to Ustream, as promised, though the company says there's a 20-second delay for streaming video. (You can see Contour's live stream on Ustream, here). The Cerevo will be out starting Janurary 21st, for $299.
