1. The message might be lost.
2. I can make all the people offline in one click :o)
3. We can also make 1 packet go, 1 packet come back, 1 packet go

By the way, why did it take so much time to finish?  It's about 2 back 
and forth packets, it should take a few hundreds of ms (about 2 RTTs), 
isn't that right?
