Yeah that could be an advantage to a display-only type mechanism.
But then a disadvantage is that you would still need to do an actual mirror before your object was actually finished. So for example if you wanted to do some tweaks and export each tweak to a mesh file you would need to do "tweak, mirror, export" repeatedly instead of just "tweak, export"...

It could be possible to set something up similar to that even if it was "real objects" being mirrored - if there was a special symmetry mode that you turned on or off there could maybe be some special logic that the mirrored objects behaved similar to locked objects until you exited the symmetry mode.
One thing that is somewhat complex with a symmetry feature is that it would probably be good for some particular commands to make a single longer object when symmetry was on rather than it only being a strictly mirrored half.
For example with a curve it is easier to make a symmetrical curve be completely smooth if the curve is created as one single long curve rather than as a half piece that is then mirrored.

Thanks very much! Yes, actually he is here now and doing really well, his name is Zane.
