Make MoinMoin running on Google app engine
I'd like to use Moin with the free application hosting engine of Google (see http://code.google.com/appengine/).
As Google's App Engine doesn't support normal file access this feature request depends on Moin's storage engine refactoring. Maybe this could be taken into account before finishing the refactoring. I don't know if the persistance model of Google's App Engine offers enough features to use it for storing the wiki. Maybe a SOC project could analyse this and port Moin to Google's App Engine.
I'm sure making Moin run on Google's App Engine will spread it's use considerably, as Google offers free application hosting.
This seems very hard to achieve right now because Moin lacks a storage layer. GAE apps cannot write to files.
Will hopefully get easier after GoogleSoc2009. (moin-2.0)
