Not really. The lightweight resolver daemon in BIND9 is actually just
the standard name server, albeit in a different guise. The lightweight
resolver protocol (lwres) uses a different port number and packet
format for handling lwres queries and replies. Currently lwres only
has three operations: a ping function to test the server is there and
get the version of lwres it supports; a getaddrsbyname and
getnamebyaddr functions. No doubt more functionality will be added
over time. And lwres packets are sent via the loopback interface,
which means there's just one server to use. There's no rotation
capability, at least not yet.
