No, you don't have to do it into separate streams. Instead, stream a
sequence of messages each of which has either an m1, or an m2, or an
m3 etc. This basically ends up being (tag) (message) (tag) (message),
where the tag is effectively identifying the type of message.

All you need to do is create the wrapper message, and the rest should
work fine.
