Does anyone know if SCTP is suitable / in use by any games? It supports streams to work around the head-of-the-line blocking problem TCP runs into and it also supports opt-in unreliable delivery for game data. On the surface seems ideal for games, though I don't know if its getting much actual use.
Nobody who's in it for the money wants to be the first one to prove that SCTP can be deployed at scale. Application developers don't want to have to sort out getting a working SCTP implementation installed and configured on the proprietary operating systems they target, and past the firewalls of all the bottom of the barrel consumer routers.
