I wonder if the PS3 supports PCI Express?  I am working on a PCI
Express card for a work project that uses SFP fiber transceivers for
the card to card link.  I am able to move about 210 - 240 MBytes/sec
over the single link.

I am using a Altera Stratix II GX which is quite pricey (BGA with 1508
balls!), but PLX makes some PCIe to local bus bridge chips that would
work for a PCIe to fiber connection between a PC/PS3 to Mercury board.
 TI has a nice 1.5 Gbps serdes chip for the fiber transceivers.
