One of the next features we will be adding is a integrated chat platform which will also function on mobile devices to transmit anonymous communication. The communication can be in several forms including sending media messages across the network. This service will be called whoRU as you will not be able to trace back to the original sending location. The users on both ends will also be able to create a permanent username for their particular wallet just like any other instant messaging system.
So when you want to talk to a group of friends you can setup a chat room similar to ICQ, skype, or hangouts. We already have the mobile chat designed and ready to go from another project we completed in the past and are currently integrating it to utilize Ruble's network for transmission. This is 1 example of the type of features we are adding to the network and would like suggestions on.
