Note that Firewire is always PCI connected, so we don't preclude using
it as a regular network adapter.  It just requires the proper driver,
and perhaps a special library to use it effectively.

A major limitation of Firewire is the lack of switches.  A secondary
problem is the curious architecture of the communication, which is
oriented to repeatedly transferring a frame buffer or moving a disk
block rather than message passing.

Now that gigabit Ethernet adapters are under $100, Firewire seems to
have missed the opportunity to be a network infrastructure.
