I was wondering if there might be away to add in the detection rail's to work with the [Message] sign's. I would like to be able to make message's on the rails to be able to Update the player on the Cord's and to let the player know when there is turns coming up and what's not.
Shouldn't be to hard, Most plugins have a spot to just type in a item id to allow that block to active it. Example: Craftbook's Bridge would allow you to add an item id, allowing you to create bridge's out of cobble, stone, sandstone. Etc. etc. If that item id was not in the list then the bridge would not work.
I can see this as kind of a cool idea but detector rails would make it harder. would need to make it simply activate in same way moving does. Added to track: http://track.emc.gs/issue/EMC-907
