NI has a reputation for fiercely protecting their patents. They sued The MathWorks over Simulink in a lengthy and hard-fought case and won in a jury trial in 2003. This is why, to this day, you can't change source block parameters via dialog box or other visual or "control panel" means while a simulation is running in Simulink. After that court decision, NI used litigation (or the threat of it) to subdue (or acquire) certain program vendors with block diagram style user-interfaces.
My guess is that at some future point, new additions to Ettus radio will be offered under some type of business-oriented licensing model that ensures a software revenue stream for NI (in addition to the radio hardware). That has been NI's model; in following this company since the mid-1980s, I don't see it changing. -Jeff _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
