I have always thought the qemu set of console things very awkward to
deal with.  pipe, in particular, is very awkward to use because pipes
have poor semantics for this.

Would it be useful if I implemented a facility for xenconsoled to make
an AF_UNIX listening socket for each console it handles ?  People who
wanted to talk to the console would connect() to it.

Multiple connections would be supported a la screen or tmux, although
of course for your application you'd use a lock to prevent multiple
access.

Ian.
