Mode 6 and mode 7 *should* have been included in the NTPv4 spec.  There
is effort underway to get them back.

I have no problem with mode 7 - it is a vendor-specific way to interact
with an NTP daemon.  Granted, I haven't heard of anybody else ever using
it.

Mode 7 has traditionaly been a binary protocol, while Mode 6 has been an
ASCII protocol.  There is no *requirement* that mode 7 use a binary
protocol.

Mode 6 stuff SHOULD be documented and specified by the RFC.  It MAY be
OK to carve out some space in this specification for vendor-specific
usage.
