APPLICATIONS
• HTML5 applications hosted by a WebBox
• User authenticates with WebBox directly in-browser
• Browser receives a session token
• Changes are made directly by the app
• Developers use “webbox.js” to simplify authentication and
access to webbox

APPLICATION INTERFACE
• External (non-browser) applications that use HTTP/
WebSockets interface
• Token based authentication
• User grants permission to an app via webbox, using a token
• The app then has permissions on a box
• User can signal to an app through the webbox WebSocket
• Developers user “pyWebbox” library for python

COMMUNICATION
• Similar interface to
applications - persistent
two-way comms using
WebSockets or one-off
HTTP calls
• Users can give permissions
to other WebBoxes/users
• Rich platform for real-time
collaboration
• Challenges:
• ID providers
• Shared versioning across
webboxes
• Global naming for shared
objects
• Network traversal/mobile
IP
Work in Progress
