jrash06 - If you are referring to the new Lithium Messenger offering - yes.
In fact, we have a customer already live with this deployment pattern. Simply said, there is a web hook you register to receive new messages and an API to send a message - so essentially you just relay messages in both directions.
Note that there is a server side solution for this as you ask, but our client-side SDK allows registering handlers for events -if that is part of your use case too.
When you are interested, I can get you more docs (we have published them yet).
