Roland always has interesting stuff at the show. This year they were showing their new $2000 portable production station the VR-3  that functioned as a video and audio mixer with cool touch screen interface that converted the output to standard USB so it can feed any USB compatible app such a Ustream.tv, Adobe Media Encoder, or other live stream or recording tools. Granted this is standard definition but for streaming, it provides some great remote production capabilities in a small and inexpensive package.
