Stephen,

I haven't found a way to "push" an ics file to google; however, you
can tell google calendar to add a calendar that is based on a specific
url pointing to an ics file and google will periodically load that
file and update the calendar.  The problem with this is that, although
it works just fine, the url must be generally accessible (no
authentication support).  Of course, you can obfuscate the path to the
file so that it won't be found easily but this is only security by
hiding...  It's also not clear how often or when google checks that
file although it appears, from my limited testing, to be at least once
a day but not much more often than that.
