I'm developing a multilingual site, too. It works like this:
* browser language preferences are usually used to determine favorite
language
* users can click on one of 3 small flags to override browser preferences
with a different language
* all data fields on content objects are stored as dictionaries like this:
context.sampledata={'de':'Einige Daten','en':'Some Data'}
* Data fields are inserted into pagetemplates using a special metal-namespace

xmlns:zope="http://namespaces.zope.org/zope";
xmlns:i18n="http://namespaces.zope.org/i18n";
i18n_domain="mpgsite"
