问题
I am trying to understand if/how this works.
Can SignalR and NServiceBus be used together to support full duplex on a web farm where the request could be sent from a server then later the response would come back but the user may be on another server.
The use case for this would be a user submits a form which then takes a while to process say 3-5 minutes. During that time the user is doing other things and could be switching between servers due to load balancing. Once the process is complete it would send a response back which would show a notification to the user.
If there are some articles on this that would be great.

Allow me to refer you to Roy Cornelissen's great blog post on this very topic:

Yes,
What you need to do is configure a scaleout-backplane for signalr so that messages can propagate between the nodes back to the user.
Here is a document that describes how to do it: http://www.asp.net/signalr/overview/performance-and-scaling/scaleout-with-windows-azure-service-bus
PS: there are other scaleout options besides the one used in this document, it's up to you.
