Are there any OpenSource pool implementations for mining multiple currencies at once?

Question

bitcoin

Actually, I’m interested in whether there are open implementations of software for creating your own mining pool, similar to p2pool.in , but not only for bitcoin / litecoin, but also for other currencies (ideally, for the maximum). For example, I understand that p2pool.ru can handle many currencies and is based on the p2pool code (although I noticed only two currencies in the dock).
