You should check with the blogger of PokerInChile http://pokerinchile.blogspot.com/, who spent 9 months there and developed his game -- mainly online. Also check out his blog of life in Santiago... http://home.comcast.net/~mniesse/
There's also The Poker Pilot blog, http://pokerpilot.blogspot.com/, a Chilean guy who would be a good contact for your re: games.
