Daniel, I hate to disagree, but at the URL included below, there are some
drivers that support IP over the FC Arbitrated Loop or Fabric for the LPxxxx
HBAs.  I was days away from trying it some time ago, but our networking
group finally installed Ethernet segments in addition to the main Token Ring
segments (!), so I didn't have a real need to move that IP traffic onto the
SAN.

Steve, if you try it, please let us know how they work.  Also, remember to
massage your routing table!
