[Openais] firewire

[ray klassen]

well I have the 1.3.0 version of corosync seemingly happy with udpu and 
firewire. The logs report connection back and forth between the two boxes. But 
now crm_mon never connects. Does pacemaker not support udpu yet?

pacemaker-1.1.4-5.fc14.i686 
(I switched to fedora from debian to get the latest version of corosync)

I'm hesitant to suggest using firewire as a transport as your the first
person that has ever tried it.  If multicast is broken on your hardware,
you might try the "udpu" transport which uses UDP only (udp is the basis
for all network communication).
