I've coded this time ago..
--- cut here ----- template

in the template just set the available languages and the preferred
ones, then use this kind of links in your pages:
general.jsp?link=pippo
and pippo_xx.jsp (where xx is the foreign language) will be called,
if the browser language is the default or the language is not
supported pippo.jsp will be used
Just an idea
