How to rip hundreds of CDs?

I'd like to take, say, a hundred CDs and make FLAC copies of them, storing them on my homegrown NAS. I also recently came into possession of an old 100-disc CD changer (no digital out). I certainly could hook the CD player's RCA jacks to my sound card's line in and just cycle through all of the CDs, but that's ugly since I'd be going digital-analog-digital. Any way just to capture the raw digital signal off the CD player's D/A converter and feed it into some sort of serial device (usb, db9 connector, etc.)? Anyone ever tackled something like this before?
