I wasn't implying that we should use their real time stuff.  In addition to
all the real time stuff, they have created Qt widgets which do graphing,
which we could use.

As for real-time, it is independent of the widgets we use for graphs, but
someone could look into getting gnuradio to be real-time aware.  That would
be another good, if more difficult project to work on.
