Non-critical, but nice for: * Putting up X minutes remaining warnings on the confidence monitor * Displaying now and next information on the projector between talks * Playing a stream, broadcast from another room. If there was a way of slinging the odd JPEG (or MJPEG stream, for the room-repeat use-case) at the HDMI2USB, then the BBB could be dropped entirely.Gigabit Ethernet is full-duplex, so I can't see why we couldn't do some type of incoming stream (even pretty high bandwidth) without effecting the output in any way.

Sorry not been reeding email during the Mini-Conf. Fantastic! Tim seriously that is great, thank you so much for your feedbackI am pretty certain that with Ethernet fully working then we can make Opsis do pretty much anything we want. Having something like a Beagle bone connected will allow us to do pretty much the same until such time that Opsis boots from FLASH / Ethernet becomes available etc etc.
At the start of the week I was expecting to use our existing twinpact solution as the frame grabber, instead we ended up using an Atlys, attached to a laptop and a confidence monitor. The laptop dealing with programming at boot time, and transcoding the MJPEG steam to 'DV' to be passed up to DV-Switch.
We were able to use HDMI, DP (& DVI) and VGA as our input sources using a number of adapters, and we ran a VGA feed to the projector again using an adapter.
I believe that we only had *ONE* device that didn't automatically pick up and 'just-work' with our selected 1024x768 resolution (IIRC this was a Chromebook) and that was probably because it didn't want to do such an outdated video mode ;-)
The system was stable and worked for the entire weekend and already IMO surpasses the twinpact solution. And this is going to get better...
