Once you disable the HOSTLISTURL and delete all the keys that your peer has 
accumulated in ~/.gnunet/data/hosts/, just re-start gnunetd. Then there will 
be only one public key (and the address of the peer!) in 
~/.gnunet/data/hosts/ -- which is your own. Copy this file to the other peers 
that are going to form your "private" GNUnet. Restart the gnunetd's to make 
them see the change in data/hosts/. 

Hope it helps :-)

PS: Eric's GNUnet-archi tools also prompt the need for an easier way to put 
GNUnet peers into a pre-defined, non-open topology for testing. So I agree 
with Igor in that we should put this on the to-do list (or on Mantis).
