So... Let's try to summarize things a little bit. People make claims about what the XCore is or is not suitable for on a modern computer. With that in mind the following points seem to stick out:
Not suitable for:
* Graphics
* SATA
* Network
* USB 2.0
* Classic Amiga Emulation
Suitable for:
* Audio I/O
* USB 1.1
The above assumes that there is a sensible interconnection between the XCore chip(s) and the resources of the system (DMA, Interrupts, address and data lines).
Did I leave anything out?
