The LDM at SSEC already does.

The pqing(1) decoder is intended as an example of how to write a
decoder -- so you should feel free to modify it in any way necessary to
accomodate your needs.
Offhand, I don't know of any problems that might arise by increasing
the MAX_CIRCBUFSIZE parameter -- but I haven't looked closely at the
pqing(1) code.
