XSite Pro itself is aggressively marketed: After you download the application, you get no less than 12 overly friendly follow-up emails, some of which try to upsell you on related services.

So to answer my own question: If you are a non-technical user and you feel that affiliate marketing is a good way to make money online, XSite Pro will make it possible for you to test your marketing prowess with a minimum amount of technical fiddling. Your websites will not win any design awards, but they might convert users into paying customers and net you affiliate fees.
