We've deployed a bunch taps in our network and now we need a platform on which to capture the data. Our bandwidth is currently pretty low but I've got 8 links to tap, which means I need 16 ports. Has anyone done any research on doing accurate packet capture with commodity hardware?

A hardware based capture card is the only way to get to any real throughput. Check out Endace cards, that will let you do line rate gig e or better and has native libpcap interface. You also may want to check out WildPackets cards.
