xm weather feed

We need a simulation of this.I just flew to and attended a seminar on nexrad weather.Only xm provides a composite nexrad image-all fbo's (wsi is the contractor) , weather channel etc. only provide nexrad base (due to boaters that have more say and $$$ into the picture).The seminar explained not only the benefits of composite xm vs. base but the fact that the last 11 or so commercial convective disasters could have been avoided with composite nexrad- superior to info radar (used presently by airlines) or even stormscope info-this seminar made a believer of me.
