Just an idea, is it possible to make a plug-in that makes redstone ignore physics and travel upwalls and roof on the buttom side...just a thought
Refer to this thread about what you want. http://forums.bukkit.org/threads/req-vertical-redstone-formatted.47656/
If you're doing this for a specific project, you might look into some of the remote redstone plugins, I have one in my signature.
Although remote redstone is possible, what you are asking for is not. Unless you have Spout/Client Mods...
