Thanks. I'm not sure either, it would require two concurrent requests
to be processed, but AFAICS oidentd only uses a single netlink socket.
Perhaps multiple running instances or something else using the inet_diag
interface?
    

Since identd serves requests from the outside world it is
quite possible for two identd instances to run simultaneously
serving two requests.

I'm not familiar with oidentd but this is certainly pidentd
works.

Right, I forgot about inetd. Thanks Herbert :)
