There are a number of possible solutions.  It sounds like the AIO
might be what you want, but I would ask someone local if you are
unsure (in other words, don't just take my word for it).

You could add anything that speaks ADAT, assuming you get the PCI/PCIe
card with ADAT connectors on it.

What latency are you talking about?  The only latency this adds is
electrical switching and media conversion + travel time for the
optical signal + the DAC/ADC.  The sound quality of Behringer tends to
be lower than other solutions, but this should work.

This sounds right.  If in doubt check with RME.  The compatibility of
the add on boards is listed on this page:

Never heard of such a thing.  I would not trust it, but I tend to be
skeptical of such kludges.
