I think what people are actually using now for the most part (as almost 
everyone uses a laptop not permanently connected to the intranet) is the

We could make up a rule "always go through host X" (X being one of the 
macbroys/lxbroys) and hope it is the simultaneous access from multiple 
hosts and not the fact that it is laying on a NFS which makes it unreliable.
