it does sound from what you describe that the rarp request is going
out on a device not attached to the network.  	i've booted dual-nic
nodes, but never with one nic hanging out network-less.

yes. single point of software and process administration, elminiating
version skew of kernel and system libraries, presenting a more
'mature' computational model to the developer (slave nodes that are
true slave nodes, instead of full linux installs).  

I'd love to see a debianization of scyld.  it's one of those things i
mean to do 'when i have time'.
