you dont need an ilok or rc tube (yet) to buy it, just an ilok account. you can transfer licences to your ilok when you get it. i had to do this last december for a sale on trigger, and am doing it again since i dont have an ilok 2
ilok2 required to use it, not required to buy it. you can buy the licence, then get an ilok2 whenever you can.

I'm not going to buy it until I know it works on my system, AND I like it.
I've already spent $70 for a 'demo' of VCC that hasn't arrived yet. I have an iLok2 already coming.
