libvirt users - Dec 2014 - serial connection between two guests

Hi
    Is it possible to drive a serial connection between two guests ? For 
example, the virt-io serial channel used by guestfsd. Can it be driven 
by virt-io serial connection from another VM ? How do you attach the 
same device on host as server in one VM and client as another ?

    Any details on how to go about doing this ?

Thanks
