If we ever get back to defeating the enderdragon, I'd rebuild the xp farm there as well. So there's not much point in having individual xp farms...

If there are questions about the mob trap as such, feel free to ask. It seems like everyone is just assuming it is completely broken, which is hardly the case. It's just that teleporting anywhere near the thing will break the filters -- this is a known minecraft bug caused by the way the game saves redstone when it unloads the chunks.

The best solution is to turn those chunks into 'spawn' chunks using a Bukkit plugin (since Bukkit broke the in-game ability to spread spawn chunks), but the overlords haven't responded to that suggestion, which is why the trap remains closed.
