(b) Consistent with the intent of the United States Congress as articulated in the Unlawful Internet Gambling Enforcement Act of 2006, the intermediate routing of electronic data relating to a lawful intrastate wager authorized under this subtitle may not determine the location in which the wager is initiated, received, or otherwise made.
