At some point I am hopeful we will have some boards that can interface a 
USRP daughterboard to the beagle expansion connector. Chris sounds like 
his guy is getting somewhere. (The problem with senior projects, they 
are due at the end of the year)

Issues that need chasing for USRP support, Angstrom is using libusb-1.0 
(or what will become that) which breaks the GNU Radio usrp driver. I can 
hack around it and build the old version, but I really want to see 
gnuradio get fixed since the libusb guys have indicated people need to 
be moving to the 1.0 version.

In the next few weeks, I'm going to look at moving data in/out of the 
beagle via SPI. The best we can do with the beagle would apply the MMC 
interface on the expansion connector.

For really serious SDR work, I think the answer is to use the Gumstix 
Overo line. The connector on the Overo products let you connect to the 
GPMC (General Purpose Memory Controller, I think) interface. This would 
let us treat the FPGA as memory.

I haven't worked through all the MEP info, but I'll be glad to help you 
work through Beagle related issues. Intel must be stopped :)
