Verify that udpOptions isn't actually exposed to users. Currently a few channelfw UDP channel functions like host access lists aren't implemented because they don't appear to be visible.
Revisit SO_REUSEADDR in UDPConfigurationImpl. The channelfw sets this to false via UDPNetworkLayer, but that leads to bind errors when a port is shared by TCP and UDP.

Should work on this before beta
