Sooner or later, regardless of how perfect the hardware is and how great the OS performs, you will have to reboot. At least once or twice a year to update the kernel and/or world. Even in such rare occasions several minutes of additional downtime per reboot (in my case) are not justifiable. I know that in a perfect world this downtime could be scheduled. But I prefer to keep the option to quickly reboot my systems when necessary. 2 vs 10-15 minutes downtime per reboot really makes a difference. How you bind the aliases doesn't really matter - you always end up waiting the em driver to reset the card on each alias. And don't get me wrong, I do use em for years on many machines having one static IP or a few additional static aliases and it works great. It just doesn't fit well in mass-alias configurations.
