Can I distribute posts automatically within a network of sites?

So here is what I’m trying to figure out. I would like to create several groups sites using Multisite Content Copier. Then from one site in group “A” create a single post and have it automatically be distributed/copied to all the sites that are in group “A”… and so on for group “B”, “C”, etc.

Question #1: Will this plugin automatically do this?

Question #2: Does the post get multiplied in the DB or does it just pull in the post data within each individual site?

Thanks!!
