How do I subscribe publish with fast data publishing using WCF NetTcpBinding

I am trying to get some guidance and a sample on this:

I have a subscribe - publish WCF service, the service is hosted in a Windows Service. The data the Windows Service processes is being sent to subscribed clients - by the service it runs computates and automatically pushes to all subscribed clients. Also for some methods I need to use callbacks to Client Requests from Service. However I also need to publish the data the Service is continuously generating through it's tasks (once per second sending updates to the clients - I am using the Callback method to do this and you guessed it when more than one method is sending lots of data I get a crash of the communicationobject. I read this WCF CallBack Blocks other Callbacks (on stackoverflow), My scenario is different in that I have multiple methods pushing data (about 30 rows x 12C) every 1 second. Since my Client hangs and the CommunicationObject goes bust I can not publish. I would like to know if I can just have a DuplexChannel for the subscribing and general functions and then when I need to publish from the service just add a separate Channel maybe create it on the fly in the service and send the data? If there is anyone with any experience or samples of this I would appreciate it.

Or maybe you can tell me I am all wrong in this and WCF will send callbacks at this rate to multiple methods with no problems and here is a sample how to do that. My current settings are: It is a singleton service - running 24/7 subscribers are stored in a dictionary. InstanceContextMode=InstanceContextMode.Single, ConcurrencyMode = Multiple, UseSynchronizationContext=true NetTcpBinding. Any help is appreciated.
