FreeBSD single-user mode

LeavesHello

I am new to this list so please pardon my elementary questions.

I wondered if conserver works in single user mode 'out of the box'
on FreeBSD.  If not, can it be adapted?

What is the connection model involved?  One master server with
serial links to the target computers?  Or is the console piped to
TCP or Ethernet over the server?

thanks,
Myles
