The alternate method for implementing string values in outvalue
is already there, just commented out (see below). I also made
changes to remove any $ characters from the beginning of channel
names specified by the orchestra, to avoid confusing hosts.

I do not really know what you mean by the host not knowing about
the channel name, but the separator in the (disabled) code below
is the '\0' character at the end of the channel name.

int koutval(CSOUND *csound, OUTVAL *p)
{
    if (csound->OutputValueCallback_) {
      if (p->XSTRCODE & 2) {
        char  text[2048];
#if 1
        /* a hack to support strings */
        /* FIXME: check for buffer overflow */
        sprintf(text, "%s::%s", p->channelName, (char*) p->value);
        /* NOTE: with 32 bit floats, */
        /* the magic number is rounded to -987654336 */
        csound->OutputValueCallback_(csound, text, (MYFLT) -987654321);
#else
        int   n;
        /* alternate hack to support strings */
        /* FIXME: check for buffer overflow */
        n = sprintf(text, "$%s", p->channelName);
        strcpy(&(text[n + 1]), (char*) p->value);
        csound->OutputValueCallback_(csound, text, FL(0.0));
#endif
      }
      else
        csound->OutputValueCallback_(csound, p->channelName, *(p->value));
    }

    return OK;
}
