It should not be necessary to support multiple associations to support multiple protocols.  Each channel should be able to have its own protocol.  

It would be really unfortunate if any extensibility mechanism for Data Channels to support (at least a limited class of) additional protocols required browser extensions.

Agreed that random (or completely general) protocol support requires exposing the SCTP API, but I would be happy with supporting "many common" protocols (even in restricted modes); with the ones I gave as good examples.
