Google friendly geo redirect technique?

[rgardenti]

Hello,
I need advices to optmize a customer's site for Google, that is actually using a Java Script geo redirect to target specific countries. Example: www.website.com is the main page, and indexita.htm is the location where the java script redirects italian customers...
I have some doubts regarding this situation, first because the index page is absolutely empty (it only serve to redirect customers to a specific regional page..), and also because making use of a Java Script to redirect visitors is always a tecnique that scare me...
What is your opinion about this?
Any suggestion to make this situation SE friendly is greatly appreciated.
Thank you
