Loading scripts into child prims

Question.

Can llRemoteLoadScriptPin be used to load scripts into linked child prims?

PS: I added a note at the bottom of the wiki page.

Background.
As you know each script adds sim load, but things like llSitTarget are not copyed when you make a copy of an item. This means that there are a lot of idle scripts everywhere. My sim has over 3000 scrips someplace in it. *Innocent look*

I am making theater seats and I don't want to have to add and delete the scripts each time I copy the seats so I am thinking of using llRemoteLoadScriptPin to drop a updating script into the seats and then have them remove themselves from inventory using chat.

This is similar to how the Autobahn scripts work

yes it can load into child prims.
but not sure how its with pin.
you must need to know child prim key at least llGetLinkKey(integer link)
But if i am not wrong you must have pin on eash prim to dont tink the root pin is seted on the child prims..
