        The Netburner NTP sample app works well enough for basic home
use, although I get better timing performance out of a fleet of hand
modified Soekrii.

        I've been modifying NET4801s to include internal Motorola Oncore
timing receivers (this is a tight fit, but doable, in the factory
cases), or to break out their second serial port for connections to 
external reference clocks.  (I have one connected to a TrueTime TL-3 to
use WWV as a backup to GPS, but it can also be a travelling GPS NTP
server with, say, a Garmin GPS18lvc connected.)

        You can make your own sub-$150 NTP server -- I'll spare the
list the details, but those that are interested should see:

        Feedback is appreciated -- I've only spent about an hour on
this doc, and it assumes a lot of familiarity with FreeBSD.  I will
try to flesh it out more as I have time.

        Cheers,
