To decrease delay in meetme:

1. Use a good hardware timing source.  Zaptel card, or if ztdummy,
enable USE_RTC (it's in the source in head, look for it)
2. Use cvs head or 1.2 beta, there is at least one meetme delay fix that
did not make it to 1.0 I believe.
3. Use hardware interfaces, not voip.  There are known, yet to be fixed
issues with delay on some voip connections.
4. Use meetme with q flag.  The entry\exit tones and admin menu add
delay.  These still are reported and not completely fixed.
