I want to amplify on this point. The number of "useful things" you might 
want to do with a real-time sample-stream in the context of DSP and 
radio is very, very large, nearly infinite, and that "near infinity" 
expands as we learn to do more useful things (because of the 
standing-on-the-shoulders-of-giants effect).

So, having a finite frame (Gnu Radio) and expecting it to, 
out-of-the-box, address any *particular* aspect of that 
near-infinite-sea of possibilities is unrealistic.

Using a "proximate analogy".  When you encounter the C++ compiler for 
the first time, you may notice that it doesn't, "out of the box" 
automatically know how to implement a spreadsheet, or a database, or any 
particular item in the infinite-sea of applications you could write in 
C++.   Gnu Radio is the same.  It's a toolbox. A very rich toolbox, but 
a toolbox, nonetheless.  There's no magic "make my answers come out" 
button.

When one is working in one small corner of "wireless" or "DSP" or "RF 
systems", it is often tempting to think that your particular corner, 
whatever it is, constitutes "the biggest class of application", and 
expect the tooling to be "born knowing" how to deal with your particular 
class of application.  It just isn't realistic.

This is a general comment, not directed any anyone in particular, and 
one that I've made in the past, and will probably make again from time 
to time.
