Following on from the "Simpleporter", I bring you "Simpleporter Network".
This is the easiest sim-wide teleporter ever. You can drop as many teleport pads in the sim as you like, and once you've given each pad a name (to allow the traveller to select them) you don't have to configure them again. If you want to move them, just move them, the network will be updated. If you want to delete one, delete it, the network will be updated.
There's no notecards to configure, no setup dialogs, no coordinates to copy, the teleport network just figures out when you've changed it and adapts to you, instead of asking you to adapt to it. You don't have to remember that there was a pad in your skybox when you move it, or on that parcel you have over the other side of the sim when you sell it. Just treat it as another piece of furniture.
Simpleporter Network is available from my vendors, the Coonspiracy stores, and from my main store at Skyhook Station in LostFurest dAlliez. Just teleport to the big blue crater in the south of the sim, or look in my picks, or follow this URL: http://xrl.us/skyhook23
