That 5th Circuit case is interesting. You can find it at:

It wasn't brought by the Justice Dept. It involved RICO lawsuits brought by 2 internet gamblers looking to avoid their losses and, actually, these 2 were chosen as test cases from 33 identical suits that were pending in Louisiana at the time.
I guess internet poker players' greatest enemies are themselves. We might see more of these types of suits, perhaps brought using general state anti-gambling laws, which are much more vague than the Wire Act.
