Answer 1

It is in principle possible via Native Messaging.

You can have a native app specifically designed to talk to your Chrome app, but the downside is that the native component cannot be bundled with the app in the Web Store. You'll have to use a separate installer.

Note that the above documentation is for extensions, but the corresponding calls are mentioned in the apps documentation as well.
