Actually, we do need good time sync algorithms.

We had a demo of a wonderful music application (called TamTam)
yesterday.

We want the kids to be able to play music together, well synchronized.

We'll get much better synchronization between the machines during a
performance if they have good synchronized clocks than if TamTam tries
to work around the lack of such synchronization, by sending packets,
which will often be delayed in the mesh.
