How would people get to the translated version of the home page? If it's by clicking a link and these pages are noindex, then it's pretty safe I'd think. But if you try to automate the transfer, there are some major pitfalls and I'd urge you not to that.
As an example, when I stayed in a London hotel they were using a German ISP for their internet connections. For several sites, I could no longer get an English version of the site because they kept sending me to their German pages.
