How do you replicate a website, to provide Affiliates a copy of your site, if they do not have their own? Do you need a Dedicated sever setup, or is this possible on a Shared set-up? Is this even possible using Joomla?
I am building a Membership website using Joomla, I have done some research and most of the software I have found is either set-up to provide link tracking for Affiliates.(By adding Banners or a link from their own site) or MLM software that claims to to replicate a website, but does not provide info on how this actually done. I presently am using a Shared Server. Linux Redhat with phpsql and Apache. If Joomla is a issue I was thinking I could create a sub-domain in HTML for some sort of replicated landing page, to allow my Affiliates to get tracked for there commission. What do you think is the best or most common way this is done?

Don't let anyone replicate your site. Provide affiliate links, banners, etc and tracking capabilities. Give a turnkey solution to affiliate marketing and the only marketing you'll get will be from affiliates looking for turnkey solutions. Amway dropouts, basically.
