Akvetch, I don't know how "smart" INVN's management is, but if they are smart, and the way they have exploited their current niche indicate they are, then from here one should not worry. Typically, a start up company starts with a unique product that gives them command in a given market place. That allows them to build an infrastructure, including distribution channels. From there, they have a number of options. They can use the technological base they have to expand to new market places (such as for instance, rapid checkup of small baggage in public buildings-of course much more compact and less costly, but much greater "market universe"), or look at the market they already service and see "what else they need" and use the distribution channels (and service organization they build around their current product line) to pump in whatever their existing client need (even if such product have no technological congruence with their current technology). I am sure that they have a number of people working on different strategies to convert their current unique window of opportunity to a permanent status of a growing corporation. Probably, using a hybrid of these two approaches.
