I'm not sure why the transport failed to initialize here.  If you run 
with DCPSTransportDebugLevel set to 6, the detailed logging in the 
transport libraries will probably give us a better idea of where it's 
failing.

Start with tests/DCPS/Messenger.  It's very flexible and, based on the 
arguments provided to the Perl script, you can select a representative 
configuration that you'd like to test.

For the simplest setup, the hosts should be able to use their own 
hostnames and peer hostnames.  That is, the network should have working 
DNS (or some form of name resolution).  When the participants coordinate 
over InfoRepo discovery (which is used by the Bench tests) they default 
to using hostnames and not IP addresses.
