I never responded to this, but yes you can get security with named
pipes. CreateNamedPipe() supports a security structure when it is
created. It depends on what security you want to set up on how best to
implement it so that it doesn't look like a wart on the side of BIND10.
I managed to hide most of the ugliness in BIND9 but it takes time to
design in a consistent way.
