I've become the de facto internationalization expert at several companies and it's always rough. Everyone wants sentence structure to be simple and will fight you when you insist on something like interpolation instead of fancy string concatenation. Like Yoda, you will sound. Hmm!

At the very least you will hire outside people to do the translations after you get the code in place to utilize them.
