[Zope] Best way to do multilingual web sites ?

Hello, After quite a lot of searching, I found few informations about multilingual websites with zope. So my question is : what are you guys using to build "complex" multilingual websites? I have a common part and a per langage part of course. How should I maintain this? Is there an acquisition trick that could help? I already tried transparent folders and mirrowing folder, but transparent folder doesn't help a lot, and mirrowng fodler doesn't have ftp support... Any strategy in use? Thanks in advance, Philippe
