My point wasn't that you can't timing or make market calls on the VIX, you certainly can. My boss is still kicking himself that we didn't load up on calls back when the VIX was around 11. But to make a "long term", which generally means >1 year, call on the VIX is silly.
They won't ever have an ETF product for the VIX because the VIX is a percentage number, not an index in the sense that it has a base level. Maybe the guys at Claymore will come up with something like that, but I doubt it would fly in the marketplace, especially given how their marcoshares are working out.
