Have in mind that the servers should be in different (sub)nets (some registrars even demand that fact for official domain setups). I do not see on the posadis site within the feature list anything different from that established scenario with master / slaves. The feature list is pretty identical with what bind offers. > > > I would like to try a fail-over pair if possible.

The slave(s) is for redundancy of the DNS information and the slave(s) automatically synchronize with the master, on which the DNS information is administered. You can too run a master / master setup, but have then to manually care for current DNS information on both servers as no mechanism will do so. > > > Some internal admins want a GUI based DNS.

Making changes in the bind zone is not that difficult and I don't really see the need for a GUI. Though there is software: Fedora ships system-config-bind.
