I currently have two PCs which I use as GigaStudio slaves, each with a meager Audiophile 2496. Both machines can give SPDIF audio output, and I'm curious if my Mac Pro host can (with the right audio interface) accept the input streams from both.

I think I've seen audio cards which offer more than one SPDIF input, but I've also read that this causes sync problems. There's also the imaginable possibility of using more than one audio card, each with an SPDIF input.

Does anyone know if any of the above are technically possible? I'd rather not switch the two PCs over to lightpipe or MADI cards unless I have to.
