It does not only look good, it's a *very* good idea.
By the way, the XS1 is not really a DSP, it more a microcontroller with serious DSP capabilities (it has a 32x32 multiplier with MAC instruction which is extremely good, but most of the instruction set is more oriented to general processing rather than signal processing)
Now, the idea of this board is excellent, because the XS1 are painful to use by amateurs. It has a ground pad under the chip which must be soldered, and this requires oven soldering...
I am discussing with Thorsten since a long time about the idea to port the MIOS on XS1, but we were blocking on the soldering problem. Now, it seems to be solved... and MIOS may exist very soon on the XMOS target.
