Well I think this amazing energy and productivity will last a very long time by watching the CEO in action. But as for how long before hitting a dollar, I would have to see how it moves on the first couple big PR's to gauge that.
Maybe 5 to 10 years. $1 means $1.5b market cap; play the momentum. .05-.1 is more realistic target in the short term if multiple contracts are signed and real revenue realized. If cuban's get in expectations will change dramatically
