A company that has the clever software (Score 2, Interesting)

In a recent eweek article ( http://www.eweek.com/search_results/0%2C3685%2C%2C 00.asp?qry=jaalam&site=eWEEK - sorry about the lack of html I am still mainly a paper oriented person) a company called Jaalam was mentioned that has a product called AppareNet that uses the ICMP packets to find out the health of networks and provide trouble shooting and status of networks. I actually saw an early demo of their product and it was impressive how it found latency issues, duplex issues, and bottlenecks across our company WAN just by doing an analysis of the data contained in the standard ICMP packet. It was also impressive that it did not trigger any of the firewalls along the way that look for scanners and such.
