[Opensim-users] how hard is it to add nested linksets or equivalent

[Serendipity Seraph]

One thing that bugs hell out me is that an object that is a linkset cannot
be added as a subpart of a more complex object without adding its linkset
prims to the overall object.   Consider a car with wheel linksets and other
linksets.  It would be great to script the wheel standalone and yet have it
part of the car without some hack of having it track the car object and
stay in proper position relative to it as a separate object.   It would be
nice to remove and replace a wheel as a single operation no matter how much
of a fancy linkset the wheel itself is.   Many 3D tools today do allow this
capability.   How hard would it be to hack it into opensim?
