Binding Xml File to List Of Object?

Hi VbForums.

I will keep my question short and am hoping for quick answer if I'm lucky.

If the title doesn't explain the question sufficiently, I will elaborate...

I have a List object which contains instances of objects which implement a common interface (IAccount). I would like to implement a way where if I add an object to this list, a corresponding XML file is updated with the new object. Conversely, if an object is removed from the list, I would also like it removed from the XML file. So, a list that is bound to a XML file which could be on the users harddrive or on a webserver. I would like it to be this way so that the state of the list can be maintained when the program is closed.

Thanks!
