Hooray, it works!  org-icalendar-force-UID + gcaldaemon gives nice
unidirectional non-interactive syncing with google calendar.  Here's a
snippet from the log:

gcaldaemon has a very nice intuitive GUI config editor.  The only
gotcha I found was that I had to hack the shell wrappers to use a
newer java binary than the one on my default path.
