Question: Is the server externally accessible too?

[beruic]

The possibility to push files to the device from another, by letting them share credentials and port numbers would open up for some interesting use cases for multi device file sharing on a local network.

The server is not accessible to the local network, see #12.

Allowing one app to write to another's filesystem directly would tightly couple them. If an app needs to receive information from another app, it should expose a well defined interface, which is not the purpose of this plugin.
