Yes. The server part is simple. If the client is working, it can pass on
the time at a stratum of one more than the server with the *.
[I think with a little work in the config file, you could make a server
only or client only.]

Probably.
There is an endless debate about how many servers you need.
With 3 servers, 2 can outvote a busted one. But that's 3 working servers.
If you are using 4 servers, you still have 3 when 1 is down.
With 3 servers, you don't know which one to use if one is down.
With minsane 3, you need 3 working servers.
With 2 local masters, you need another server.
