Merged Mining Disadvantages What are the disadvantages of merged mining? I'm very interested in p2pool and since I have to "run my own server" I've been considering enabling merged mining.

Besides the obvious administration overhead and learning (which I chalk up to being a hobby), what disadvantages are there? I wouldn't be reducing my BTC hashrate would I?
The disadvantage of merged mining is the additional coin daemons you have to run in the background. They all use disk space, memory, cpu cycles and bandwidth. A more annoying issue is that most of them are no longer maintained and have bugs. You may find that they crash frequently - at least namecoind does.
