How can I localize modules in my DNN installation...?

Must I simply follow the procedure shown for the language pack and i end up translating all that's on my portal or do I have to go through each module individually?

Plus... every time there is a module upgrade must I go through the whole translation process again or must I only translate the missing parts...?

Has anyone thought of "splicing", so to speak,  professional low cost CAT tools such as wordfast to DNN's infrastructure... this way all repeated segments will be automatically inserted by the program. This will add consistency to translations by means of translation memories and will give project leaders the possibility to translate the same command in the same way throughout the application.
