What about a XMPP "groupchat" for changesets?

It's easy:
....login...
<presence to="osm at conference.osm.org/osm"

<message to="osm at conference.osm.org" type="groupchat" id="58">
<changeset>  ....</changeset>
</message>

The OSM Server should send all changesets to this groupchat.
If  somebody wants the changesets he can connect to the groupchat and 
will get the changesets.
If the  messages get an incrementing serial number, it should be 
possible to load changesets if
they are missing because of whatever.

I don't know if a jabber server is able to handle the load. But facebook 
also uses ejabberd (free software) and it's working.

If somebody wants to implement pubsub he can use the input from 
groupchat and load it to pubsub. That should be easy.
