@niclas ssh still looks like ssh. the idea is just to make all traffic look like a minecraft game which is less likely to be considered interesting. It's an obfuscation tactic. It sounds like they've even gone through the trouble of comparing browsing traffic to normal human players to try and make the packets used by a non player look more like a regular game play session.
Looks very procrastinated. If the censored side allows SSH, a ssh tunnel requires nothing special to do same/similar thing, and why not tunnel over port 8080 or other often accepted ports?
@niclas but https can be encapsulated within Minecraft. Technically I think any traffic could be encapsulated. In the video I watched they were using tor over minecruft. This would be useful in countries where tor is forbidden. The one exception they said was actual in game traffic needed additional context applied.
