Multicast discovery does not work properly on multihomed Windows 2003
Packets are sent to unpredictable network interface that results in brokers loosing connection
with each other.
It would be nice to be able to specify network interface for multicast socket right in the
discovery URI.

So transport connection definition turns from 
{code}
        <transportConnectors>
            <transportConnector name="openwire" uri="tcp://0.0.0.0:61617" discoveryUri="multicast://224.0.0.1"/>
       </transportConnectors>
{code}
to
{code}
        <transportConnectors>
            <transportConnector name="openwire" uri="tcp://0.0.0.0:61617" discoveryUri="multicast://224.0.0.1?networkInterface=eth0"/>
       </transportConnectors>
{code}


I added support for interface/networkInterface for multicast on multihomed hosts. See attached
patch
