Irrespective of the use of RFC1918, I always advise end-sites to use  
split-horizon for nodes which aren't meant to be publicly accessible  
simply to avoid leaking potentially useful information to an external  
attacker.  But in my personal experience, I've found that the  
overwhelming majority of sites which could benefit from split-horizon  
don't know what it is and therefore haven't implemented it.
