+Shairport 2.0 actively maintains synchronisation with the source. 
+If synchronisation is lost -- say due to a very busy iTunes host or a very congested network -- then Shairport 2.0 will mute its output and resynchronise. The loss-of-sync threshold is a very conservative 30 ms -- i.e. the actual time and the expected time must differ by more than 30 ms to trigger a resynchronisation. Smaller disparities are corrected by insertions or deletions, as described above.
