Just a sudden synaptic spark: how about a time server that periodically
connects to several user-specified time hosts, and logs the average and
standard deviation of their values. Not too generally useful, but
real-world and exploits asynchrony well.
This idea was inspired by a nice little Windows time server called
AboutTime that logs entries like this:
