dynamically updating the forwarders with bind/rndc

Hi,

Is there a way for bind9 (or planned for bind10) to dynamically update the forwarders via
rndc? I believe currently the only way to do this is to rewrite the config file and then
cal rndc reload.

This is not something that lends itself to automating based on a network manager based
network that receives DHCP updates and needs to reconfigure the forwarder based on the
obtained DNS server options.

I know unbound can do this using unbound-remote forward a.b.c.d.

If a patch for bind9 would be written to allow this via rndc, would it have a chance of
being accepted?

Paul
