As much as I like the idea, I would think there are so many legal issues (no pun intended) involved here. Aside from the multimedia presentation aspect; good, clean recordings that are labeled well of everyone involved, the ability for the judge to mute all of the mics if he has a bench meeting, getting the right camera where you want it etc.
I can't tell where you are from but if you are in the states you may want to check out javs.com. They have been doing courtroom automation since the VCR and have an incredible system. The engineers and original creators are geniuses. You would be doing yourself a service to at least investigate what is out there.
I appreciate the advise. Let me add some info for you, there will be no mics and no cameras. This is strictly to show video across 6 monitors using DVD, Doc Cam, and laptop inputs. I just am always looking ahead and know that with the automation part of the lmce, if i can blow the commissioners away with this UI for controlling the court room, then they will be very open to using the technology in other parts of the courthouse and jail for automation and control. I will def check out the link you posted and thank you.
PS> I understand the legal aspects as I do have a system in the county courtroom that records audio and does movi tele-vid to the other courts in the state, I am currently designing a "movi room" in the jail so that the prisoners will not have to be taken from one building to the next. We are a very small county so I am always looking at implementing linux into our infrastructure for cost reasons as well as security reasons.
