Application Compendium - Generic Concepts

Inspiration for Innovation. A collection of other possible end-user and network-centric applications.

The OpenCloud Application Compendium is a collection of communication applications that can be realised using OpenCloud’s Rhino product suite.
This collection of applications not only demonstrates the powerful flexibility of OpenCloud Rhino, but more importantly it shows that while internet companies appear to have the edge in communication innovation, network operators (fixed, mobile and multi-play) have enormous potential for to leverage their voice, messaging, video, data and billing capabilities and other network assets in valuable new ways.
Some of the applications presented here are available as fully productised “off-the-shelf” solutions, others have been developed as framework applications by OpenCloud partners,  ready for rapid finalisation according to your precise requirements. The rest are just concepts to inspire further innovation.
