add unified and expandable messaging system
Reading all the posts about different messenger apps tells me, we need a easy expandable messaging system (similar to the good old Web OS days :-)
- It should be easy possible to add a new messaging service to it via market
- All messages should be visible and handled at one place
- The system should remember the favorite way to communicate with a contact
- The system should support secure communication (end to end encryption, OTR, etc.)
