Most of the software use is internal, actually. There is a limited market to actually capitalize on the software because everyone gets so locked-in from various vendors, so friction and moving costs are high - not to mention social signaling of using similar software packages.

Which is all well and good, really. By developing better internal software packages, we move faster and more efficiently and churn out better research and products. I have no desire to sell the software that powers the engine that will overtake my competitors. Maybe in five years when we're the market leader and we can sell the software for a few million dollars per year. :)
