A Software Defined Radio attached to BeagleBoard XM

I was wondering whether anyone would know as to the best choice of software defined radio to use with the beagleboard xm?
Wondering whether a DBSRX daughterboard might be best solution?

I have used QtRadio http://napan.ca/ghpsdr3/index.php/Main_Page on a XM quite some time ago and posted a video on Youtube.

I have had the HiQSDR with the ghpdr3-alex servers running on a Pandaboard and accessible on the internet.
