Filip,

Sorry for the confusion.  I am testing this on my local machine at the mome=
nt.  I am assuming in an environment with multiple machines I'd have the ac=
tual IP address of the machine here correct?

How about my settings for following:
- channelSendOptions
- NioReceiver maxThreads
- McastService frequency and dropTime

Anything terribly wrong for a production environment?

Thanks,
Jim
