Tonight we demonstrated Jaiku running on Google App Engine, a new development environment that enables anyone to develop Web services that can scale up to millions of users using Google’s massive server infrastructure.

The announcement was made a short while ago at a campfire event here on the Google campus in Mountain View. Robert Scoble broadcasted live video from the event using his Nokia phone; a production-quality video will be posted in a few hours on the Google App Engine site.

Jaiku will be fully deployed on Google App Engine in the near future. More details on the Jaikido blog.
