It seems that the newer 7.0 ASA/PIX OS does support the inspection of the Gnutella protocols like Limewire. The older PIX OS clearly stated you had to use NBAR to filter it out. But I see no mention of anything other than Gnutella and wanted to ensure that the reference to Gnutella in both the SNPA courseware and the online Command line reference reflects the inspection of all Gnutella protocols as students are asking!! Will have to set it up but have no time at the moment.
