One problem with that cunning plan is that using custom device states
doesn't work.  The code for handling device state changes in app_queue
is looking for a forward-slash in the device name, and returns if it
doesn't find one:

loc = strchr(technology, '/');
    if (loc) {
       *loc++ = '\0';
    } else {
       ast_free(sc);
       return 0;
    }


I've worked around it by modifying that particular bit of code, though
in a way I'm not sure I'd want committed to mainline Asterisk SVN (which
is why I haven't submitted it yet).
