I would rather go with the LXRT smart feature of RTAI [http://rtai.org], 
which provides hard-real time in user-land with POSIX API (or whatever else 
with appropriate "fusion" skin). Hard-realtime programs are also allowed 
to make syscalls to (non hard-realtime) Linux kernel, in which case LXRT
switch to softrealtime until completion of syscall, and back to hard-realtime
upon return. Quite nice.
With a SWIG magic touch over LXRT, even GNU Radio python scripts should
be able to come into play. 
Oh, and it's GPL and free (as in beer!).
