/**
* In-VM transport.
*
*
* This transport lets you deploy services in a servlet-like
* environment within the same VM. Unlike the local transport,
* which deploys a new server instance every time a new transport
* tube is created, in-VM transport maintains a server instance
* outside the transport, allowing multiple clients to talk to the
* same in-VM service instance.
*
*
* For this reason, in-VM transport requires explicit "deploy"
* and "undeploy" operations.
