aiolibdatachannel

Create a real-time collaborative document editor using the Python package 'aiolibdatachannel'. This application will allow multiple users to simultaneously edit a shared text document in real-time, similar to Google Docs. The app should include the following core functionalities:

1. User Authentication: Implement a simple user authentication system where users can sign in or create an account.
2. Real-Time Collaboration: Users should be able to see each other's cursor movements and text changes as they happen, ensuring a seamless collaborative experience.
3. Document History: Maintain a history of all edits made to the document, allowing users to revert to previous versions if needed.
4. Conflict Resolution: Handle situations where two users attempt to modify the same part of the document simultaneously, ensuring that both changes are eventually applied without loss of data.
5. Offline Support: Allow users to continue editing the document even when disconnected from the internet, syncing changes once reconnected.
6. Notifications: Send notifications to users about new collaborators joining the session or when conflicts arise during editing.

To achieve these functionalities, you'll primarily use 'aiolibdatachannel' for establishing and managing WebRTC Data Channels between connected clients. These channels will facilitate real-time communication between users, enabling instantaneous sharing of cursor positions, text updates, and other collaboration-related data. Additionally, integrate asyncio for handling asynchronous operations efficiently, ensuring smooth performance even under heavy load conditions.
