In 1997, before I'd used ntpd I had chrony on a pair of systems
used for dialup connections peered together. Later, ntpd on my
servers worked without any problem using the two chrony sources.
I've not been able to successfully peer between chrony and ntpd
though, but I don't really have spare hardware at moment to
really test this out.
