Hrm.  Monitoring Services does make sense.  Kind of a tough call.  Will
give it more thought but probably keep in Linux since anyone wanting this
service probably knows exactly what they are looking for.

Agreed.  My documentation was lazy.  Will improve.  Thanks for the specific
pointers.

About the sqlite db, I honestly don't know much about how it compares to the
logs.  From a cursory glance at the code it looks basically like what you said,
a structured rendering of the logs.  Will make some kind of note about this.

Speaking of, the log output looks like "rasdaemon: <message>", so it's probably
just as good to put this in the syslog rather than a dedicated file.  How can
one do that?
