With our setup, certificates are handled by Amazon elastic load balancers. A single ELB with a cert for 100 domains using SAN is easier to manage than 100 certs on a few servers using SNI. I'm not saying you should design this way from the start, but this is what we grew into and SAN works for us. I only wish the limit of 100 per cert was higher.
