This could be a workaround for the newly introduced aliases.
I've added the "-" alias to the other xml file reading and writing tasks: http://trac.openstreetmap.org/changeset/6844 Now it is possible to do wget -O - http://... | bzcat -c | osmosis --rx - --bb ... --wx - | bzip2 > excerpt.osm.bz2 which performs considerably better than Apache's bzip implementation in Java, which is built into osmosis.
