What this effectively means is that the virtual domain name, or a hostname, can now be used to identify the network end point. This allows one to serve different SSL domains with the same IP address. Working with virtual servers (like OpenVZ containers or XEN dom's) you might need a load balancing or a proxy solution to be able to run services from inside those machines through your host's single public IP address.
