If I put two or three messenger agents under the same messenger service
container will they all communicate. If users at site A log into a
messenger agent at site A and users at site B log into a messenger agent
at site B will they all be able to message each other?

I just found this is not the case if they are in a seperate messenger
container. Or is there a way to get them to communicate during a migration?

Thanks,

John Jakus
