A while ago I wrote a small QGIS plugin, to control a running JOSM or other OSM editor that supports the remote control API from QGIS. I finally got around to add it to the official repository so that you can now install it with a few clicks from inside QGIS.
In case you are interested in doing something similar, I use the following command line to create the necessary ZIP file from the git repository:
git archive --format=zip --prefix=OSMEditorRemoteControl/ \ --output=~/OSMEditorRemoteControl.zip master
