Can this be used remotely? Edit: Yes, after turning on Remote Management on my second mac I was able to log into it using Remote Desktop, account root and no pw.
It only works after getting physical access once.
edit: I should say, I did test this locally first so I don't know if a fresh machine that hasn't done it will do the same thing and let a remote account enable root.. Would like to hear if anyone tested it remotely WITHOUT doing it locally first.
While it's unlikely, there are probably plenty of users who have done this for some reason or another.
Don't underestimate a user's ability to blindly do things like this by following arcane instructions in attempts to fix an unrelated problem.

They seem to be remotely accessing the machine to both set and then use the root account.
Not sure if you'd get different results after logging in as root at the login screen...
