Yes, provided that they open the fifo while they would be both attached 
to the same vnet.  Once the sockets would become open the processes 
could reassociate to arbitrary vimages, while the sockets would remain 
bound to their original vnets for their entire lifetime duration.

As an alternative, we could / should introduce an extended socket() 
syscall where an additional argument would explicitly specify to which 
vimage/vnet the new socket should belong.
