I considered it. 10' of chain like you see is about $20, so it's actually a pretty similar price to a cheapo bike chain.
I may have enough worn out chains to do this. Maybe on the back corner of the house, out of the wind. I might actually run a very short piece of chain down the center of the chainring, to keep water moving down the line. Though a little splashing might be better for the plants beneath it.
I don't necessarily want the rings and cogs to rust but I'd like them to look weathered. I guess time will tell.
