There is no intention to ever remove the Grid system from the Sindome Game Concept. The errors you are experiancing with the web-based grid interface are, as I said, due to an unfortunate hardware failure. Prior to that they were working quite well, with only minor bugs as one would expect in any Beta situation. (ie: On Sindome, perpetual BETA!)
As to a discussion of the Matrix, I am willing to talk about what we already have discussed in the past, even if some of it is already in topics in Ideas.
If you have played SuperHappyFunLand, an in game entertainment element for corpies (we are still planning to expand it to RED as well some day) you will have glimpsed what our 'VR' or 'Matrix' system will be like. In a nut shell what we do is create a set of rooms, take a snap-shot of them, and then archive that snapshot to disk. We then call that shap-shot into being every time that 'game' or 'room' or 'area' is accessed via the SuperHappyFunLand system.
As it stands now, the SHFL games are 'holo-room' technology. (Similar to current VR Cube technology, only suped up a bit.) For personal systems I picture either trode/google interface or Nnic (neural network interface chip) interfaces, each having advantages and disadvantages. (trode being more affordable and safer for your braincase, and Nnic being faster, more powerful, but more expensive and dangerous.) These personal VR devices would link to a 'cyberdeck', a high grade computer that handles the processing of raw image data and the like, feeding it to the users interface device. The deck then connects to the Gridworks Infrastructure or to the Matrix Infrastructure as needed by the user.
The difference between Grid and Matrix is simple. Grid is non-emersive. Matrix is fully-emersive.
As to the avatar concept, that is already in place in the SuperHappyFunLand systems. (SHFL was designed as a testing ground for the back-end systems needed to do a lot of Matrix elements.) Basically the initial Avatar for a player would be a 'snap-shot' of their physical description. This is already possible, though there are particular issues that need to be worked out with things like getting damaged in the virtual world, and how does that transfer over to the physical body or not. But that is a side issue more than anything.
Basically one's avatar is potentially redescribeable in the Matrix to be anything one wishes, quality being dependant on skills, equipment, and the like.
So, n8n, there is not a lot to 'get rolling on'. A good 90% of the back end systems are in place. All that is required is for a coder to link it all together and get it working. The project is Kevlar's baby at the moment. He will get to it as soon as he able to, once his busy life sorts it self out a wee bit.
I repeate, we will NEVER 'do away with' any XML-LambdaMOO system. The GRID will ALWAYS be a part of SINDOME. Why you ask? Because not everyone can afford to get the gear, the connection, and the skills to run the matrix. It will be an exclusive area to corpies and high grade criminals. For the dirty mud people there is the Grid.
