I've consolidated the revision of RawSocket transport in the WAMP Advanced Profile in the spec:
The revision brings the following benefits. RawSocket ..
1. can run with different serializers on 1 port
2. can run along with WebSocket and LongPoll on 1 port
3. now has transport level ping/pong for fast connection loss detection
4. now has negotiation for maximum message sizes
With 4., it should be possible to bring WAMP to tiny microcontroller using less than 2KB RAM.
The latter might require a different serializer (one that works "in-place"), but that can be done later: https://github.com/tavendo/WAMP/issues/72
If there are no final objections, we move RawSocket to "stable" in the AP.
This will then:
Regarding Autobahn, this will need updates to AutobahnPython and AutobahnCpp (the only 2 Autobahn's that have RawSocket right now).
