The Future for online applications. My hope.

I hope that very soon we will start to see applications start letting the user control their own data.  When you find that application that you would love to use, just to find out that you can’t get the open source and maintain the application yourself but rather give control to the owners of the application and keep all your data with them.  I am hoping for an option in the future to allow users to maintain their own data, and just data for now.  The application stays on the owners server while allowing each user to set up their own database with the correct structure.  Once the user signs up for the application they can enter the database connection and username and password for a successful connection.

Now the user has the control over the data.  No more worrying about never getting your data back again.  No more being held hostage.

There are huge benefits to the applications owner(s) too.  Now there would not need to be huge amounts of server storage space to pay for, now you only have to host the application and maybe a small database or 2.  This would make prices cheaper.  This would make people happy.

There would be issues with speed of data transfer but the internet, and computers are only getting faster and more powerful, and should be able to handle these connections in the very near future (if not now).

I think this would make supporting the application much easier too.  If you know the application is not having issues you can be confident that it’s on the end users side and then you can charge for support or the client will end up having to fix their issue.  So now you have less money and time invested in support and the ability to make money supporting end users with their problems.

There are many ways people can say this is a terrible idea but everything one of those ideas can be proven not to be a problem with the proper precautions.  Thoughts?
