The delivery of the Google App Engine may turn out to be the biggest story of this year.
Google has always told its new employees to imagine what they would do with unlimited capacity. Now, as of April 7, it's telling application developers the same thing.
The key question is, of course, what's the best way in? You can take your company into GoogleLand, or you can go in through a another door. An open source door.
That's what Appcelerator is offering. The Atlanta-based Java tools outfit is porting its software over via its developer network, and offers a step-by-step method for using its tools on the service.
Not to mention a running demo application.
I fully expect lots of other folks to offer similar side-doors into Google Apps very soon, so this isn't an ad for Appcelerator. The point is that questions about the business usefulness of Google Apps may be greatly overblown.
