> My idea is to control adc/dac directly from an FPGA (lots of them,

yes, i thought so too...
something like this:
______________
| |<-> *2 <->adat
adc *1 ->| |<-> *2 <->spdif/aes-ebu
|fpga ->i2s |<->xmos avb
dac *1 <-| *3 |<->some phy <->madi
|_____________|<->some phy <->ieee1394

*1 you need external adc and dac, because lowcost developement onboard
adc/dac have only 10 or 12bit resolution...

*2 adat to I2S boards (properiterian codec)

spdif/aes-ebu to I2S boards
http://electronics.dantimax.dk/Kits/Digital_audio/11319920832.html
http://electronics.dantimax.dk/Kits/Digital_audio/12906353062.html

*3 MSB/LSB switching can easyly be done with fpga
