As long as the strings were unique, they could be in whatever format people wanted. Of course, you should also take a look at VMware's VMCI.

To allow other transports to be loaded with vmci_transport, we register the vmci_transport as G2H or H2G only when a VMCI guest or host is active. To do that, this patch adds a callback registered in the vmci driver that will be called when a new host or guest become active. This callback will register the vmci_transport in the VSOCK core. If th...
