Wouldn't listening to/soliciting router discovery ICMP
messages on your hosts take care of this? See RFC 1256.
Supposedly FreeBSD `routed' already does this.  When you have
multiple routers in your network this ought to be better than
hardwiring a default gateway on your hosts.  But you
shouldn't need to run RIP or OSPF on your hosts.
