I am not sure RNWK would drop that much (to $15), but with the lock out date, it sure doesn't look like it will take upward bounce.
As far as the support, I think it could drop to high teens. I sure welcome it drops to $15, but since a lot people have bought it in the mid-$30's and above, I don't think they would want to take a loss so fast.
Hey, take for what it's worth, but I really believe RNWK will survive as a very good company. Longer term investors shouldn't let the volatility scare them. I sold my way too early, so right now I am neither long nor short (I don't short stocks). I sure would take another plunge with RNWK if it would drop to around $17. I sure hope it could drop down to $15. That would be a perfect buying opportunity.
