[spam] for the n-dimensional space approach, i'm thinking on the idea of agents being fixed in some dimensions, able only to navigate others, and using sum of axial distances rather than the sqrt of their squares to measure.  this could help develop experience around things having conceptual, similarity, and other forms of distance that we can't navigate; unsure.  I was thinking of mapping things like cameras or chat windows to different spaces in the virtual model world, and how their physical location may not be well represented: the systems would learn it.  another idea is including "portals" inside the coordinate environment, fixed things that communicate information with other coordinate environments.
