High Performance Software Defined Radio (opensource)
An Open Source Design
The HPSDR is an open source (GNU type) hardware and software project intended 
as a "next generation" Software Defined Radio (SDR) for use by
Radio Amateurs ("hams") and Short Wave Listeners (SWLs).

http://hpsdr.org

There are GnuRadio developers which are in contact with or collaborate with 
people of HPSDR.
They use some of the verilog sourcecode of the USRP for their FPGA in their 
boards.

Gstreamer Quadrature library (opensource):
libgstiq is a library with  Gstreamer  plugins for use in software defined 
radios.

libDSP (opensource)
libDSP is a C/C++ library of digital signal processing routines, including 
standard vector operations, digital filtering, and transforms.

flex-radio (commercial)
Company building software defined radio frontends (SDR-1000) for use through 
the soundcard of a PC for the IF.

Comblock (commercial)
Hardware oriented commercial company delivering blocks to build SDR systems
ComBlock modules are small commercial off-the-shelf modules which are  
pre-programmed with essential communication processing functions,
including modulation, demodulation, error correction encoding and decoding, 
digital to analog/RF, RF/analog to digital, formatting, data storage
and baseband interfaces.

Thu GnuRadio GUI you are referring to is called GRC, written by Josh Blum

If you need any other kind of info, please let me know.
I have done some presentations on GnuRadio and Software Defined Radio and I am 
preparing for some GnuRadio courses that I will be giving.
It would be appreciated if you made the paper public and available somewhere on 
the web.
