This has been happening since 1999 by the NAAPO (the same group who ran the "Big Ear"). They had a cluster of helix antennas being fed into a VA Linux Systems Hardware Cluster doing analysis on radio astronomy events: http://www.naapo.org/Argus/docs/docsmenu.htm http://www.naapo.org/Argus/docs/docsmenu.htm I volunteered there from 2004-2008. I believe that the cluster is still active today.
