  It wouldn't work in the original situation where you can only ask *one*
question (which implies that you can interact with the guards just once).

  If you can ask them limitless questions or interact with them in an
unlimited way, the task becomes trivial.

  I thought about another way of restricting the situation: The guards
will never answer to questions (or to actions) which would directly reveal
whether they are lying or telling the truth. (The solution to the original
problem never actually reveals which one is lying and which one is telling
the truth, and thus it's still a solution in this situation.)
