I would make the language a foreign key, but aside from that no real
input.

However, user localized content is probably going to be a *ROYAL*
pain... In my experience the biggest difficulty was QA for the
actual text itself.

Presuming your objects have foreign keys pointing to strings, I
would delegate this to the loc function, kind of like:

	$obj->find_related( what => { language_id => $lang } )->content;

or somesuch.

You could create a helper method as a custom DBIC component, but I'd
keep it so that it always must explicitly get the language as a
parameter.

At any rate embedding the notion of the current language into the
DBIC row object sounds like high maintenance dependency injection.

By constraining the actual multilingual decisions to only the view
layer, and leaving everything open ended in the model will make
things work smoother when the application is taking a meta view on
it's localization. I can't see a reason for which language or a
default language to ever be a model concern, but I can see quite a
few reasons why not =)
