You will want the local disk space for the directory where you have Bro installed, I usually use /bro on clusters.  The remote.log file is still kept locally on each worker and proxy node and the Bro binary is copied to each when you do the "install" command.  

There is a setting for BroControl named "HaveNFS" which is commented on here:

OSU ran very similarly to that for a very long time.  I suppose it was actually how the first production cluster (with BroControl at least) was done but we backed away from it a bit due to all of the problems I was encountering.  In the hands of a more experienced cluster admin, I expect the results would be much better. :)

I think you'd probably be fine with this deployment scenario.
