Stylistic -

I try not to use "!" if possible
(typographically, it is a small char - easy to miss),

and the >0 hopefully makes it obvious that
we are creating a boolean expression.

(not that there is any other option here,
  but when ints are erroneously used
  in place of bools, there is)




I might just change the hostname correcting to use:

     if (m_localhostname == NULL || m_localhostname == "my-unique- 
identifier-goes-here")
