Emailed Google calendar invite is an even bigger bag of pain. They include two ".ics" attachments (one called "Mail Attachment.ics" and one called "invite.ics", leaving you wonder which one to use). If you try clicking the "Yes" in the email invite and you are not logged into the correct Google+ identity you get an HTML splash that says "Google Calendar invitations cannot be forwarded via email" (and no links to break out of that. If you load the ICS into iCal you can accept the meeting (and the sender seems to see that, so there must actually be no useful account based security in play). I thought about filming that one- but I don't want to go through those steps again. I think it is fair to evaluate Google tools in a mixed environment. To assume a pure-Google environment is to assume away all other options and choices.
