Will they blend? Local vs. Remote ZIP File

This workflow accesses a zipped file from a local URL (knime://knime.workflow/data\2008.csv.bz2) and a zipped file from a remote URL (http://stat-computing.org/dataexpo/2009/2007.csv.bz2) via HTTP connection on the web. The two data sets contain data about US flights for 2007 (remote) and 2008 (local). Both files are zipped and need unzipping. ... and yes! They blend.
