Multi seating script

I need a script to put into a round seating unit, which can seat 8 to 12 av's. the standard poseballs don't work as there seems to be some kind of conflict and av's get turned around where they're sitting.
I need to the script to be copy so I can put it into the seating units for sale, when in the units they just need to be no copy/no mod

Every prim can only have one sit-target that sets relative target position and rotation of an agent, sitting on it.
Without a sit target you can TRY to sit on a prim, large and flat enough, and may suceed after the 5th try or so, but will never sit the way you want to.

A linkset can be up to 255 prims lage, every agent sitting on one substracts -1 from that number.
A physical prim-linkset, including vehicles, can only be 31 prims large, or wont be able to become physical. Every agent substracts -1 from that.

If you are still looking for a solution, IM me. My script "The Chair Rezzer" supports multiple people sitting and sounds like it might fit your needs. It rezzes and de-resses chairs around a central table whenever people sit down or get up, and the min and max number of chairs are configurable. I have had several customers make "couples" chairs that incorporate the chair rezzer tech.
