The i18n_variables way of hacking Übercart into better language support is really neat, from a usability standpoint it is even acceptable for my customers to use.
Anyhow, it's a bit hard to figure out what variables go where. Sometimes the Theme developer module can give some hints, but often not. Now for example I couldn't figure out how to make flat rate labels multilingual. Any hints? 
It'd be really cool if you could find a way to ease up this process. Providing a ready made code snippet (to put in settings.php) making all of the Übercart core modules' variables multilingual would be great! Also some generic tool or instructions to help the process of figuring the variables out would be useful.
Merry Xmas!
