Good idea. Zope needs some more languages anyway.
Apache for example has mod_negotiation for this.

please not: the q argument is not meaningless.

I think a better way would be to implement a true negotiation mechanism.
That is, if the request comes, zope has to look for languages available
and rates them according to the language preferences coming from the UA.
Then it sends out the highest rated document, that might be the first
of the items in accept-language.
So each document (could be a folder?) schould have an attribute to
identify
its language capabilities. 

A simple branch would imply you have all documents in all requrired
languages.
I in doupt you can make this happen.

Easy with a second string.split(_.['sequence-item'],";")[0]
