What's a good UI design for administering multi-lingual data?

Question

I am going to be creating a multi-lingual website (asp.net) and was wondering how to best handle much of the administrative screen UI work where the end user will be maintaining lists of data that will need to be in multiple languages. Anyone know of any good sample applications I can take a look at?

Example scenario. I have a screen that an admin would use add a new product. The title and description would need to be stored for each language in the system and would be required in order to save. The number of languages would ideally be dynamic/configurable where the UI would not need changing each time we add a new language.

Thoughts/suggestions/examples?

Answer 1

Our previous in-house CMS used a fairly simple model which the editors seemed to like: over each input field, a thin row of toggle buttons (JS-powered) selected which language was currently being edited:

[EN-US] [FR-FR] [SW-SE] [RU-RU] [ZH-CN]
 _____________________________________
| textbox                             |
|_____________________________________|

They behave kind of like radio buttons, e.g. selecting one deselects all the others, and the textbox immediately flips to reflect that value. The buttons were small enough to fit about 16 above an input field before it started to get unwieldy.

I'd also recommend a "master toggle" at the top of the page which switches all controls at the same time.

To follow up with @mikehall's answer above, I would do something like this sketch:
