I like the concept of this patch.

I can't think of any reason why the callers of libxenstore should need
to care about how which communication channel gets used so there's no
reason for the library to defer that choice to the caller. So perhaps we
should go one step further push this behaviour down into libxenstore
itself? i.e. add "xs_open(int ro)" and make
xs_{daemon,domain}_open{,_readonly} compatibility aliases to that
function.
