One of the more interesting (to me anyway) Native American language revival
attempts is that of the Mohawks, especially on the Kahnawake reserve just
outside Montreal. As you may know, a law was passed in Quebec some years
back requiring all students in Quebec schools to be educated through the
medium of French. The Mohawks of Kahnawake, who have had a long history of
bad relations with French Canada, resisted by setting up their own school,
the Survival School, to foster the Mohawk language. This issue ties in with
the overall picture of Mohawk relations with Quebec and Canada (and the U.S.),
and you probably remember the violent standoff at Oka in 1990.
Other groups with interesting language projects going are the Cree (esp. of
James Bay, Quebec, where the giant hydroplant project is a huge issue), and
the Passamaquoddy of Maine. Finally, I don't know if the Pequots of
Connecticut are attempting a language revival (or if they even have a language
left to revive), but with all the money they're getting from their huge
casino business, it might be worth looking into.
Hope this is of some help.
