Seems that I didn’t explain well what I want to suggest.
I am thinking of an online translation tool. Such as the one mentioned above or e.g. Pootle. http://translate.sourceforge.net/wiki/
If you want to see them in action:
Pootle is used by TYPO3: http://translation.typo3.org/
and Otrance is used by OXID: http://translate.oxidforge.org/index/login/
I personally might prefer Pootle as a visitor can not only translate the suiteCRM core and modules online “on the fly”. -> With Pootle it is also possible that the suiteCRM user/admin can upload files s/he translated locally on her/his machine.
I would imagine that such tool motivates suitecrm users to participate in translating as it makes access easy.
