Now, let's say I define Scheduled Tasks for my Application, is it possible that the said tasks might end-up being run by multiple Application Instances? The reason I am aski...

In the past, I created a Django wiki, and it was fairly straightforward to make a Page table for the current wiki entries, and then to store old revisions into a Revision table. More recently, I decided to set up a website on Google App Engine, and I used some wiki code that another programmer wrote. Because he created his Page model in...
