I would just run in standalone mode.  As far as I know (and Robin will  
know better), the only difference configuration-wise between  
standalone mode and cluster mode is the node.cfg file.  If you run in  
cluster mode when you really only need standalone, you will have the  
overhead of extra bro processes running that aren't really necessary.

I would recommend that you stick to standalone mode for node and if  
you build a cluster eventually, the configuration steps necessary are  
going to be the least of your worries.
