Since this group was set up to push and develop only the bundle protocol, the group will probably need to be rechartered to allow this. Non-bundle protocol work has been ignored previously.

To consider CoAP or SPDY or websockets in dtns, it is necessary to consider how HTTP - which CoAP, SPDY and websockets are based on - fits into dtns. And since HTTP assumes full path connectivity between the endpoints, and dtns don't have that, it's not as easy as one might think...

Fortunately, that consideration and mapping HTTP to dtns has already been thought out, and has been previously presented to the group:
