I've recently posted a couple of tech articles on my blog ( at http://dougjoseph.net ) about how to remotely interact with Google services, including the remote authentication needed for adding, editing, deleting (etc) data on Google's servers.
I don't know if remotely interacting with Google services is in VineType's future, but given the way VineType already takes advantage of a lot of neat stuff out there, it might be. Especially the Google Calendar service. It occurs to me that anyone using VineType as a blog tool like I am, or even any business using it as a web content management solution, would like to also get a gCal calendar and display it on their VineType site.
Now, simply embedding one's own gCal (in an I-frame) on his or her own website is too easy. It's a cinch.
But whether or not anyone would ever have need (or want) of seeing VineType (as an app) handling (remotely) any gCal maintenance, I cannot say.
But our church website did have a desire to see that happen, and so I dug in and found out how and made it happen.
In the event it would interest you, maybe just to archive for future reference, the last two articles on my blog are Part 1 and Part 2 in a series.
Sincerely,
Doug Joseph
