Since we have free accounts on app engine, heroku etc... and even gdrive or dropbox and so on... wont it be easy for someone to write a simple web app or ipad app or something like that allows the masses to run their own wiki's without being technically sophisticated. To an end user the process could be as easy as install app from chrome webstore... specify some minimal data... and you have an app engine account hosting your tiny wiki. If tomorrow you choose to move it heroku, it would as simple as a button click and registering on heroku.
