Phil Covington N8VB has written several articles about
how to speed up the data transfer. He even incorporated
an SERDES chip into his original Mercury design (SERDES: TI 
TLK2701) http://pcovington.blogspot.com/ and has successfully
demonstrated fiber optic connection between his prototype
and his PC running at breakneck speeds. Perhaps you can get
him to comment about your PCIe idea.
