It's probably the easiest to get working right, and less EMI problems if 
done right.

Multiprocessing isn't really a crystal issue at all.
The systems don't even need to talk at the same speed, SPI is clocked 
serial, so the unit sending the data determines how fast you go.  The only 
restriction would be that device A can't talk faster than device B can receive.

Tip:  Set the slower device to be the "master".
