That sentence confuses me, James. Was it written as a question? (i.e. 
"gpsd supports these other things. Isn't that enough reason to use it?")

In my case, the built in reference drivers are handling my desired GPS 
sentences correctly, and my PPS is working just fine. They've been 
running for a few weeks without incident, and delivering a less jittery 
time than my previous installation (using the same GSP module and 
refclocks with ntpd). I'm looking for a compelling reason to change to 
"refclock shm" and gpsd on this new ntpsecd installation.

But since it has obviously been running for several weeks now, the 
urgency of my question is low. If this remains stable for a few more 
weeks, I'll probably bolt it into my production system as one of the 
time sources.

Me thinks an email list server which sits on messages for months and 
months is more of a hindrance than a help. What are my other choices to 
talk to people who care about ntpsecd? I haven't looked, is 
comp.protocols.time.ntp still active?
