I need some conceptual help.

Let’s say you have a browser open to a Wonder app (component based session). Imagine you go to a different computer and open another session (maybe via direct action) to the same application. I want to have a button (or some such) in the first window that when clicked communicates to that second independent window and enables some form fields there. The user then submits data to the application from that second window. The first window registers the submission and continues with the user interaction.

How would you do something like this? Is this possible at all? Possibly the second login could be from a mobile device and the presented browser page does not allow to do more interaction with the application than just enter some data and submit. The first session is required do wait for the data (or a cancel) and can then proceed.

Thanks for any ideas / help
