I know that's an option, I just know that having the ISO files in a datatore that's either local to the host, or on one that's also used for the VM's is going to be fast. Plus, you have the ISO readily available for additional installs. It even gives you the ability to create new VM's when remote (via a VPN connection and such).
I've also gotten into the habbit of using ISO files when installing the OS into a VM under the Workstation product. Pretty much the only time I use physical media, these days, is when I'm installing the OS onto a desktop system. I don't even use them when installing software, unless I'm forced to (which is rare these days, or when you know what you're doing)...The less I need to use the physical optical drive, the better I like it...
