Possible with Multisite?

I have a project looming, and I'm wondering if Multisite could handle this.

The main site would be in English, and the child sites would be separate domains. Most of those separate domains would be close copies of the main site, but translated into various languages and while much of the content would be duplicated from the main site, there would also be region-specific content as well.

So my questions are:

1. Can Multisite do shared content across various sites that would be translated into other languages?

2. Are there any other plugins that might be useful on such a Multisite installation?

This will be my first foray into playing with multisite, and I'm trying to minimize the breakage :slight_smile:
