Versatile Monitor Mount in a Unique Situation Ideas

Hi

I am hoping to pick the brains of you DIY'ers out there building home cockpits for a very unusual situation.   Explaining this to other people who dont understand the meaning of your flight simulation hobby comes up with meaningless answers like just use a laptop.  

Background...   About 13 years ago, I have alot of trouble to sit.   Good for about 5 min before excruciating pain hits down the spine and into the neck.  It involves multiple nerves that are stuck and cant be operated on.   But there is no way I am going to lose my 35 year hobby and was determined to continue flying.   For these past 13 years my desk is actually my bed. I did this by building a workstation next to my bed with heavy duty monitor arms that extend over the bed for the monitor and the speakers. This involves alot of counterweight options to prevent the desk from falling over.   The keyboard and mouse all wireless, and my joystick is freely used as needed with longer cables, as well as the honeycomb bravo throttle mounted at an angle from the workstation.   All very ugly setup but functional for the most part.  I fly lying down looking slightly up to the monitor.  Cant use pedals for rudder but HOTAS setup takes care of this with a twist.  Everything computer wise is simple for me since that is my background and have a fully customized  PC build.  

We are moving soon, and wish to find a better more "elegant" solution that also incorporates an option to stand and fly.  I thought I would do this with a ceiling mount for the monitor which hangs over the bed, and swing it over to a nearby standing table, however the ceiling mounts dont have this versatility even though they are "full motion", they cant extend out they only hang vertically.   

My only ideas are somehow putting the bed and desk on castors and moving things around in order to have optimal placement of the monitor.  Not so easy with cable connections everywhere.   

Perhaps other option is to have the monitor swing from the side desk.  But because I would like a standing solution , and that I am 6'8, the desk needs to be much taller than normal and therefore less stable because of the high center of gravity and the extension when lying in bed.  would need a whole lot of additional clever counterweighting.

Any other ideas would be greatly appreciated.  Budget also has to be considered since I am not working otherwise this would be simple to get some builder in here to make a special platform that incorporates all this together.  

Thank very much
