Run named on Solaris 10, preferrably in a local zone, and use svccfg/setprop
to give the named service net_privaddr privileges ( and to remove
unnecessary privileges as well ) so that it can listen on port 53
without having to be started by root.

It's easy to adapt the model at

to named.

As far as I know, there is no equivalent functionality in linux, fbsd,
obsd, hpux, aix, or any other unixish OS.
