I want the drivers to be owned by a user, Foo. Whenever the drivers are called by application Duh, I want a program Bar to run after the driver has done its work, since Foo is now running the driver. Is it possible?

You can't say a driver is 'owned' by an user... drivers are just code that run in kernel space... processes (started by certain users) can run or not that code. If you want, you can verify if the driver is accessed by an user, but that's about it.
