If you mean the PCI bus arbitrator, then unfortunately, no. It was done 
commercially for a client who owns the IP for the whole design, so I'm not 
at liberty to disclose it. However, the whitepaper for the wishbone arbiter 
is freely available.

Definitely!

I guess the caveat is with the FPGA you're limited by the size of the 
device... but you do get accelerated CPU cores and very fast inter-CPU I/O!
