Multi site multi domain (2 sites max) multi language

Hi,

The Multi site domain plugin, and yes I know it is a stupid question but is this what I would use to make Multi site work over two domains?

It is for a simple site, but I want to be able to login once and update French version of site and English version of site.

Also, I am need to know if multisite can handle different menu names, ie ones that are in English and ones that are in French.

but this question may be beyond your brief.

Regards

Rob
