I'm not really qualified to evaluate the technology, but the 4 minute
flash demo on the site states that the system uses non-BGP approach to
determine response time and load on selected links, as an alternative to
just selecting least-hop AS statistics with BGP. Check out the
'technology' section of the Web site.
