Most of NTS4NTP is dancing around the lack of per-client state on the server.

If PTP servers only support a "small" number of clients and PTP already has a 
mechanism using shared keys, it might be simpler to just use TLS/whatever to 
setup keys.

If it takes 100 bytes for a server to store a key, that's 10K clients per 
megabyte.  Raspberry Pi-s come with gigabytes so the numbers seem worth 
further investigation.

Does the PTP shared key stuff cover all the problems?  (or enough of them to 
be interesting)
