I posted this a while back on /r/bitcoin but I thought it might be a good topic of discussion here also.

I was listening to an non-bitcoin related podcast where they were talking about the possibility of avoiding US federal regulations by partnering with American Indian Tribes because they have tribal sovereignty. It occured to me that this would also be a great place for bitcoin too. A quick Google search didn't turn up any discussions on this so has this idea been thought of already?

The Bush II administration clarified that "Limitations on tribal powers of self-government are few and include the same limitations applicable to states; for example, neither tribes nor states have the power to make war, engage in foreign relations, or coin money." This does not seem to imply that they must use USD as their default currency.

In fact, the late Russell Means of the Republic of Lakotah had proposed that the nation should not use fiat currency but instead adopt a gold standard. Would they be interested in using bitcoins?
