dispense Landmarks across sims by key?

I want to be able to dispense Landmarks from several
locations, spread amongst Sims ... I'm trying to avoid
having to manually update ~25 odd places in 8 sims...

I am thinking this runs up against the same limits as
the conversation in:
/54/0c/168423/1.html

What I would like to avoid is having to duplicate the current
master object for every sim that may have kiosks to update.

I love being able to set textures by key - what I was hoping to do
is be able to give landmarks by key ...

Not sure I understand your question. This is not a problem as I see it.

- Make a server object, never, never kill it. This is is your "giver". All landmarks are contained here.
- When user clicks on any client in world, send email to server requesting the landmark.
- Use llGiveInventory in server to give it out. (works cross SIM)

You MUST know the inventory items name because you can not give them away by key. Maybe that's the problem?

I have an item that does just this that I am just finishing beta testing in, give me a holler later tonight inworld an I may be able to help out.
