the client side (nagios-nrpe-plugin) is pretty straightforward. I've 
attached my patch I'm using locally. I'm not an experienced C programmer 
and it is far from perfect, but it works for me.

* Might contain security bugs, memory leaks, you name it
* can one assume that getaddrinfo() is available on all (Debian) 
platforms nowadays? I have never done any automake stuff, and the code 
would probably become a bit messy doing that.
* one should probably code -4/-6 flags
* haven't done any testing on IPv4-only hosts (without loaded IPv6)

The server side is probably a lot trickier, especially in daemon mode.

* one has to open/listen to two sockets, one for IPv6 and one for IPv4 
nowadays. I'm not sure whether this is even possible without an 
additional fork()
* server_address might not be too easy
* allowed_hosts is probably really hard

I am ignoring all those challenges and running nrpe from xinetd, which 
works fine. I doubt this will be good enough for Debian mainline though.
