Re: Awful for millions
Of course you can have two domains on the same server both running SSL each with their own certificate, it's done regularly and if you were an ISP then you would expect to know this.
In reality though anyone using shared web server hosting (not including VMs in that obviously) is unlikely to have a serious enough web business that the difference in the search rankings that this would provide would be of concern.
