Zythos is a tasty Hop (blend).
I had it in a SMaSH from Boundary Bay over Christmas break. It has a nice piney, floral aroma.
Did they call it a smash? I don't think it's reasonable when they are using a blend. Why not blend some malt and then make a smash with that and some Falconer's Flight? 
I can't remember if they actually called it a smash, but I do know that they called it a Single Hop, and I remember them saying it was all 2-row. At the time, I hadn't heard of it, and didn't know it was a blend until I saw it at the LHBS.
With the blended pellets, it kind of blurs the lines regarding single hops. Given that you can't create that blend on your own, it is kind of similar to using a single hop.
