Ah, yes, sorry - I'd forgotten that osmosis can be used in so many
ways! We're mostly using it to read pbf files which have already been
downloaded - so I didn't know why there was any need for traffic.

Here's the command in essence:

osmosis -v 100 --read-pbf
osm/downloads/europe/british-isles-latest.osm.pbf  --tag-filter
accept-ways highway=* leisure=* landuse=* aerialway=* route=ferry
man_made=pier,jetty --tag-filter reject-ways
highway=motorway,construction --read-pbf ... many more countries ...
--merge  --buffer --write-apidb dbType=mysql populateCurrentTables=no
host=localhost database=planetExtractOSM user=import password=
validateSchemaVersion=no


Here's some of the output from:
netstat -nputwc
