[Answer To Question 3: Yes you can host it from your home server and you can send the client through email. ]
[ NOTE: As long as you know how to set up ports to open your home ip address to the public. ]
4. Question: So the most people that would be viewing-logged in at a time would be maybe say 6?

Also remember if you're going to go for more then just showing off models in a small world then you better learn a lot before jumping right into it, its a lot more work then most people realize.
Sincerely TechWiz.
