Ah, okay, you're ahead of me.  I hadn't gotten quite that far yet, but 
your thought process seems sound to me.

Your thinking seems to suggest you feel the hook should be another fifo 
out of spiceqxl_drv.so.  That would certainly be the easiest approach 
for me to take, so I have a built in desire to go that way.  But I worry 
about complicating that driver.

Why not route it through the vd_agent?
