Right - what I meant above was that we don't provide more than one
two-channel format.  Any two-channel connection is the same as any other.

While I want to see hints attached that say "This is an M/S stream", it
seems that the complexity is probably not worth it.  Those sorts of things
are probably best left as documentation.  If your plugin outputs M/S it will
have a 2-channel output and your UI or manual will indicate that it is M/S.

Unless anyone wants to chime in and convince me that more detail is needed..
