NServiceBus: Load-balancing subscribers

Is it possible to load balance my subscriber worker nodes without using a distributor? Here's what I am thinking:

Instead of having my distributor subscribe to a publication, and having each worker node "report for duty" to handle messages, what if I just put开发者_如何学编程 each worker node behind a Virtual IP, and subsrcibe this Virtual IP to the publication? Can you send MSMQ messages to a machine behind a Virtual IP?

The problem with a "virtual IP" is that you want to have a queue where unprocessed work sits so that you can monitor it, and based on that, increase/decrease the number of worker nodes. Did you run into any problems when using the distributor?
