Also, there's the age old problem of common password for everything, if one is compromised, they all are. Granted in this case, it's a private key and not password, which is slightly harder to acquire though social engineering, mainly because most people aren't even aware of what private keys are, and those that are usually know enough not to give them up. But still, you shouldn't use one key for everything either... or so I've been told ;)
