I had seen that before sending the announcement. My first read of this
draft let me think that the idea was to publish Webdav event through pubsub.
My idea is more to use different access protocol to the pubsub
mechanism. Let me emphasize the difference. I think Webdav is the most
consistent, but probably FTP could be a valid protocol to publish
information inside the bus.
If the file is big, you do not have to publish it completly: You can
only publish metadata on the bus, along with a link to the given file.
The initial need is the following: A J-EAI project is aiming at
exchanging official document over a pubsub J-EAI channel. The document
are stored and timestamped by a bus client and delivered to several
others. However, the file can become quite big and we do not want to
limit the size of the document. Embedding them in the XMPP stream is
thus not very wise. That's why I looked for another way to publish data
on pubsub nodes.
I think anyway, that this previous work is a very good basis to push the
idea of Webdav and pubsub integration further.

Yes. And being able to tie users on the Webdav server with the one of
the XMPP/Pubsub server also opens interesting opportunities.
