I think this stock is a compelling risk at this point. The price/sales is around .25 and the market cap is just 30 million. They have good products, an solid ip portfolio including over a dozen patents, and the telcos are stepping up cap ex spending, not to mention the growth of VOIP. The "going concern" stuff recently discussed is boilerplate language and has scared some senseless. However, I think there is money to be made here.
