1.9 actually had too few DLL's and resulted in all sorts of versioning conflicts when used together with other OSS libraries. It was 1.8 that had the overly-high DLL granularity. It's our hope that 2.0 finds just the right balanace.

You don't need to give up all the benefits of the fully distributed deployments that NServiceBus supports to achieve "central auditing support". You have the ability to direct all audit messages to a central location with 1.9 as well as 2.0 by setting the ForwardReceivedMessagesTo attribute of UnicastBusConfig.

Hope that addresses your issues.

NServiceBus could be a good alternative for you - reference 3 DLLs and you're done.
