* Support different sample rates.

* Support different sound file formats.

* rplayd tends to peg the cpu when it is trying to connect to another rplayd.
  This needs to be fixed.

* rplayd should play sounds while receiving them.  The reason I am not doing this
  currently is that audio headers have to be checked at some point.

* Fix regex.[ch] to compile with a C++ compiler.

* Add an attribute so rplay packets can send sound data.  This would be useful 
  for radio broadcasting.

* Support more than one audio device in rplayd.  A client should be able to
  specify which device to use.  Should there be more than more audio spool?
