I guess it is not a good idea because almost no one understands it.

The idea for the one with Ethernet was not as a pool server, but to be
behind the firewall, for the enterprise (company) time servers and to
feed the enterprises pool server. The cheap little time server would not
be seen from the Internet.

If you have a pool server, then this could be one of the time sources
for your server. If you have an enterprise server this would serve time
to it. And the enterprise server would serve time to all the clients.
This little server would not be the pool time server. Use a regular PC
Server for that. Since it was local and on the same Ethernet then the
delay and jitter would be much lower. It would be the preferred server
your pool server and in-house servers would sync to.

I guess a cheap Stratum 1 Time server is of no interest. Everyone wants
what is on the >$1000 servers. If you folks do not understand, then I
will never be able to sell it to less educated folk. That is what I
needed to know.
