emerging tech always has its set of doubters. in fact, the market doesn't always behave in rational ways. once you have someone with influence pushing a company, all the flemmings will jump aboard and next thing you know it, it's a sure thing.
VINA has a good management and a product that will fit a nice niche. what it's worth, if i knew, well, i would be heading some company by now. however, the story, technology and market is compelling for a small stake in the company. don't bet your house on it, but, it may become a nice player.

long term, the upside is far more compelling than the down.
