Dave,
I have since retired the FreeBSD server in favour of Windows 2000 and XP
systems which can provide a good enough offset for me (within a
millisecond or so). Look at the three systems here:
http://www.satsignal.eu/mrtg/daily_ntp.html
Feenix - lightly loaded XP system
Stamsund - heavily used interactive XP system
Bacchus - lightly loaded windows 2000 system, with occasional 100% CPU
load from a weekly defrag (today's defrag would not do this).

My FreeBSD system ran on a 48MB 133MHz pentium system, so not dissimilar
in power. But having a router box you could simply convert might be
easier. You can use serial-to-USB convertors and not loose too much
accuracy:

Sounds a fascinating project, Dave. Too much QRN from all the computers
here to do too much radio!
