SSL certificates for multiple web enabled devices?

I m developing a device that has a web server and uses SSL. There will be 100 s or 1000 s of these out there (so the salesman says). They will be on a private network, but how does the certificate work for this application?

Do I need a CA signed certificate for each one? Can I somehow use a shared certificate?

The customer will be setting the IP address of the device when they buy it, so I dont know in advance what it will be. It also wont have a domain name since it isnt a "real" web site, just an IP Address.

I have the SSL working and can generate a self signed cert, but the browser crys about it and says its not secure.

How can I make the browser happy without buying a cert for every device?
