I have not looked exhaustively, but haven't seen an existing plugin that does this. Basically I'm interested in something that would allow furnaces to supply redstone power while burning things. The general idea would be to have a generator that requires fuel vs the magic always available redstone torch.
I'm on it... //EDIT: Never mind. This plugin appears to be simple at first glance, but when you actually look into it, it turns out to be quite a bit more complex than you'd expect. As is stated in this thread, Bukkit doesn't have a event for when a furnace stops burning. Adding in a custom method would require a good amount of code, more than I have time to write. Sorry. Maybe another dev would be willing to take the challenge?
I think he just wants to use it for many people as a generator He doesn't want it for just one person
