What is "cost of ownership" for an object. How is it calculated? The references you provided on land impact are very good ones, and I think my original question has to do with land impact and the two "accounting systems" for the impact of prims. However, I have seen (in my Firestorm viewer, and I can't remember where) an actual estimate in $L with the label "Cost of Ownership". I think I was pointing to an 8-prim object, and the number shown was L$110. I thought it was on the edit screen, near the prim count, but for the life of me I can't find it again, and no, it was not an object set for sale (LOL). I assumed it was a number that somehow showed a periodic cost of owning an object of that land impact, based on some cost of land estimate. It was this calculation that I was looking for. I'll keep looking to find this again so that I can make my question more specific. In the meantime, thanks for the response!
