PowerShell: Create Virtual Server

Joe - thanks for those links... very helpful indeed, but it sounds like you're saying there's no way to create a "blank" Virtual Server without any profiles selected at all as you can in the GUI? Forgive me if I sound a bit ignorant - I'm a scripting systems guy tasked with writing some stuff for the networking team to use. In the GUI, I am able to create a Virtual Server by specifying only the name, address and service port - everything else is left at "None". This is what I'd like to accomplish using PS and iControl, if possible. Thanks.
