Here is the link from SSRN, and the abstract:

The recent opinion by the Office of Legal Counsel has created a lot of activity after years of uncertainty about the legality of Internet gaming in the United States. Internet gaming poses a threat of unknown magnitude to brick and mortar casinos, including Indian casinos. Because internet activities are difficult to regulate across state boundaries and national uniformity is likely to be more effective and more efficient than multiple state regulatory structures, Congress should federalize the regulation of Internet gaming. Congress should, however, consider the important role that Indian gaming has had in lifting the socioeconomic status of Indian people and improving the self-governance and self-sufficiency of Indian nations. Congress must insure that Indian tribes have an equal opportunity to be part of the future of Interney gaming.
