This fits quite nicely with the idea I had while talking with temas
Basically, the reasons that binary are good:
- useful for carrying other programs data
- negotiating binary connections
- payloading binary data
Reasons that we want binary in Jabber, and part of the stream:
- leverage the server centric model for firewall traversal.
- easier peer-to-peer binary conversations even if they are both behind
Some of this was being discussed for PASS/DSPS, so my idea was, don't
merge the binary into the XML stream, instead create a second stream
with a generic enough framing protocol that it can payload other things,
and still maintain the JID idea of a recipient.
So basically, the XML remains XML, and all current clients will not
break. But for those that want to speak and transfer things in binary,
you can connect to another port on the server, and converse in binary.
The best of both worlds. Both are streaming, both understand sending a
packet to reatmon at jabber.org/Home, but they do not mix.
Now that's something I'd get behind and champion.
