Thank you for the replies, Luke and Sean!

turning off the firewall on each and every machine did finally allow  
me to start the cluster across all my machines. Keeping the firewall  
on would be desirable, however. Using tcp wrappers I can restrict  
access to local IPs - although I loose the bonjour-names  
(machineA.local, etc - need to use IP numbers instead). When the  
firewall is turned on, the console.log records "Firewall Tool: Error,  
Start Port (600011) invalid!" when trying to start the cluster. I've  
tried to open tcp port 600011, but that didn't help. If someone  
figures out how to work snow with the firewall left intact, please  
let me know.  Nevertheless, my snow cluster is working now - big  
thank-you to Luke Tierney et al. for snow!
