What are you planning for sat morning? I am away from home but could skype or mumble and could easily put JOSM on a computer here. If you just need examples and advice on how to interpret stuff that works fine for me.

I've been creating a circle of the correct size and tagging the way as 'building=hut' in much the same way as we create a rectangle / polygon on a square sided structure and tag it building=yes. The info on the main tagging wiki at http://wiki.openstreetmap.org/wiki/Key:building shows the tag being used on an area, not a node.

I suspect that it is still being used for that purpose, and will continue to do so. Also if the building is traced it appears on the map, but if it is a node it does not. On the basis you can do a more accurate calculation on the area from the polygon & you can't do it on a node that could represent an unknown quantity of buildings I think we need;
