wiki twexter 
http://twext.cc/dev/summer-of-code.html proposes open software enabling translators to easily format bilingual text to help us learn languages. Interface enables users to easily create "twext" translations and to add new languages.
System promises to build bridges between a wide variety of languages; especially useful with songs, pithy quotes, proverbs, sayings, poems, etc.. System could integrate with variety of softwares, including multilingual Wikis..
http://twext.cc/license is currently GPL/CCL, with flexibility to host variable licenses by permission.
Twext language trading system subscribes neither to theory of grammar study (boring), nor to philosophy of "immersion" (stressful), but rather to Stephen Krashen's theory of "Comprehensible Input" http://www.sk.com.br/sk-krash.html
ONE LAPTOP PER CHILD initiative expressed interest in mentoring twexter development for Google Summer of Code 2006. Jim Gettys was interested in Alexander Gelbukh as the active mentor for the project. Unfortunately, students didn't have enough time to produce qualified applications. http://wiki.laptop.org/index.php/OLPC_Google_Summer_of_Code#twexter_language_learning_interface
ALEXANDER GELBUKH http://www.gelbukh.com/ has expressed a keen interest in mentoring development of the twexter language learning interface for inclusion in Google's Summer of Code for 2007, and will ideally convince students to begin development in the academic year of 2006-2007.
