RapidMiner integration for KNIME is now available as a KNIME community contribution build. Feel free to use it according to the AGPL3 licence.
Recently it was updated to use RapidMiner 5.2, so the new visualization options and other improvements are become available.
The community homepage is: http://tech.knime.org/community/rapidminer-integration
Many thanks to KNIME and University of Konstanz for the support during the KOS 2012 days.
