OT: I/O device with multiple *independent* SPDIF ports?

For a home project (like I have time for it) I'm implementing a virtual preamp: TV, Mac, AppleTV, DVD, etc. in --> decoding / efx processing --> multi-channel out. Things are working pretty smoothly but I've got a pile of USB SPDIF interfaces hooked up to a Mac mini which is, shall we say, not very aesthetically pleasing.

Is there any input device out there that has multiple *independent* SPDIF interfaces on it? When I say independent, I mean that they are all individually clocked and don't try to do any fancy tricks to make the audio bits all line up. As you might expect, for the most part I am trying to receive digital bitstreams, not PCM, so any clock stretching tricks will totally destroy the data.

To be honest, I'm not sure it is even possible for a device driver to present multiple streams running at different sample rates/clocks so I'm guessing the driver would have to export multiple AudioDevices. That seems unusual for a product idea but it'd be sweet if I were able to consolidate all of my inputs into one box. Has anyone out there seen such a beast?

If not, any hardware folks out there who have a recommendation for the SPDIF receiver chip-of-the-day? It's been a long time since I've done any hardware but it'd be nice to have the info for reference in case I ever need it. :-)

thanks,
stephen
