In essence, if a structure can be found that cannot have developed through natural processes, wouldn't that force us to conclude that some non-natural, intelligent agent had to be behind it?
To expand on Ned's response a bit.
In practice we could only discover that known natural processes as we understood them, under the conditions which we believe applied could not generate the structure.
Even if we managed to rule out the possibility of unknown natural processes or known processes acting in an unexpected way (due to limits in our understanding or lack or knowledge) - a difficult task - we couldn't conclude that the source was both intelligent and supernatural. Because how can we rule out unintelligent supernatural causes ? Real forensic science avoids that question by relying on methodological naturalism - a point that virtually all IDer's prefer to obscure and avoid.
(As a side note IDer's have a tendency to confuse the natural/artificial dichotomy with the natural/supernatural dichotomy. Methodological naturalism is about the latter and includes the actions of intelligent agents).
To replace evolution ID really needs to have an alternative theory. And it doesn't. With an alternative theory they would not need to rely on arguments from ignorance. With an alternative theory they would not need to falsify evolution in an absolute sense. If they were honest scientists they would not be trying to influence the school curriculum until they had a robust theory that could be shown to be superior to evolutionary alternatives in at least some respects.
To give ID it's due it could have been done on a much more scientific basis. That that is not the case is entirely the fault of the ID movement which cares about science only as a (useful but not necessary) apologetic tool.
