'sense' all avs on island?

I have a task that should have an easy answer, I just can't figure it out.

I have an island and need to give every person that arrives a notecard. I can do this by placing 'notecard stations' all around the parimeter and have them sensing to the 99m limit (it seems to be limited to 99 - is this correct?). But people might get duplicate cards and someone teleporting in might not get one!

Also the card will be changing periodically and that would be a lot of 'stations' to update.

So is there a way to have a single 'notecard station' in the middle of the island that can sense over the whole island to give out cards?

Any help would be greatly appreciated.

Simplest solution would be to have a single landing point with one station to give out notecards there. You could also divide up your land and set multiple mini-landing poitns and keep the number of stations down as well.

If the av really should be able to teleport to any spot, well, have a grid of sensors shouting to a central server and av keys showing up, and only the server gives the notecard and ignores duplicates (check the av key to a list, if not there, give, if so, ignore, then add the key to the list, maybe resetting every so often). For an island, shouts on a hidden channel should be fine, could even set up the server to send out updated notecards so you don't have to go to each one.

EDIT
Would probably be best to have the sensor prims also keep their own lists of avs, checking to see if detected before to cut down on the number of shouts to the server.

Also, the maximum range of a sensor is 96m.

Just FYI.
