ws: nope.  each conference allows up to the maximum participants.  
Maximum should be set to the smallest number supported by conference 
devices.  4 comes from the old ws-x4604 which only supported 4 parties 
in a conference.  There is no intelligence in the feature to 
pre-allocate a device that supports "at least N streams".  Hopefully 
this helps explain the parameters you found.
