Well, indeed, since I specified the CVIP address as BindAddress in httpd.conf, I 
actually can migrate apache threads, even individually. I'm not sure why, but 
whatever.

This way, I can run only one instance of apache on my cluster, instead of one 
instance per node. My next question is: how can I specify the node I want to run 
this instance on? In the rc.nodeinfo (maybe debian specific?) file, I can put 
either 'initnode' or 'all' for a given service, but I'm not sure if I can put a 
node number there. Any clue?

Thanks for your answers,
Berst regards,
