It's things like 'ypcat smbpasswd.byname' that I would be afraid of ( as
well as somebody sniffing the wire ).  Just make sure that 'ypcat
smbpasswd only works for root ( but then you still have to worry about
someone monitoring the network traffic ).

The scp option was one that I considered here as well and may well do as
a push update from a cron job on a secure server.
