Suggestions: "Multi Language Applications in CF in Theory and Practice"

I would like to ask your suggestions for preparing a presentation.

I will present a whole day class just before CFUnited (http://cfunited.com/go/classes) on “Multi Language Applications in CF in Theory and Practice”, and I would like to know what topics would be interesting to cover.

I specially would like to focus on best practices with some different techniques and share some sample applications with basic implementation and also with some well known frameworks usage such as Fusebox or Model Glue. But meantime I also would like to get your ideas & suggestions about this topic.

I am developing CF applications since '97 and I already created more than 100 multi language project and I have some experience to share in i18N & L10N. But still I am open to any kind of ideas that would be interesting for this class.

Thanks in advance.
