Slave DNS

[With No Name]

Hello *,

I have only one fixed IP from my ISP and run my own (Master) name server.

A friend from me in another Network segment does the Slave.

I do the same for him.

Now I am puzzeling arround, whether it is possibel, to setup the slave DNS
to accept any domains (including newly created) from a master...

I find it realy annoying, if I have ask every time the owner of the Slave,
to add a new zone.

Any Hints?

Thanks
