What you suggest is already operational here, but this is what happens:

- two local master NS, with replicated MySQL
- one remote slave NS (only IP allowed to AXFR)

If domain is set to "native", no notify is sent to any NS.
If domain is set to "master", three notifies are sent to all NS. Of 
course only remote NS will ask for AXFR. But we ask why sending three 
notifies, when only one could be sent?
