Answer 1

Let me dynamically server SSL certificates via domain header

There is no domain header so I guess you mean the Host header in the HTTP request. But, this will not work because

• HTTPS is HTTP encapsulated inside SSL
• therefore you first have to do your SSL layer (e.g. SSL handshake, which requires the certificates), then comes the HTTP layer
• but the Host header is inside the HTTP layer :(

In former times you would need to have a single IP address for each SSL certificate. Current browsers do support SNI (server name indication), which sends the expected target host already inside the SSL layer. It looks like node.js does support this, look for SNICallback. But, beware that there are still enough libraries out there, which either don't support SNI on the client side at all or where one needs to use it explicitly. But, as long you only want to support browsers this should be ok.
