Hello,
From what I understand your product would fit the bill but I need some clarification on a few things:
1. I am running three sub domains and want to install your product on one of them such that I can control all three from the one Joomla admin, is that possible?
2. I would like to share all of the articles and content but also would like to be able to create content for individual sub domains which would not be shared, this is because each sub domain services a different geographical area and there is a need to localise some content. Is that possible?

If not is there a product that would do this?

Very Best Regards

Gordon

1. Possible, but all sites should use same Joomla installation, so you will be forced to use parked domains, but not hosted sub-domains.
2. Not possible, you can either share ALL articles, or not share them.
But you can setup a specific category for each site and configure site site to display articles only from its category.
