Looking for overview information on the project

I'm interested in experimenting with SDR on my new BeagleBoard. However, rather than plunge in, download lotsa packages, kick off BitBake, and find myself lost in a maze of twisty little error messages, I'd like to start by understanding the overall architecture of the Beagle-SDR implementation, how it partitions functionality between the GPP, DSP processor, and external hardware, how it fits in with GNU Radio and Embedded SDR, and eventually, how to connect stuff to it. I've read the ARRL Handbook chapter on SDR, I have a general understanding of SDR principles and some experience working with SCA environments and waveforms, and I've read the descriptions of the USRP, but I'm having trouble finding any overall design information on the Beagle-SDR. Can anyone point me to sources of information on the architecture you're building here and its performance goals? (For example: If, as appears likely, you're emulating the USRP motherboard in the Beagleboard DSP, what sort of RF frequency range do you plan to cover?)
Down the road, I'd like to use the BeagleBoard and its SDR capabilities for control of a semi-autonomous remotely operated vehicle, but that's down the road. Small steps first...
Any hints are greatly appreciated.
