TTM use in North America

["Josh Fleishman" <flyman2 () corp earthlink net>]

I am interested in hearing how/if TTM (Test Traffic Measurements) is
currently being used in North American networks. Practical experiences,
gotcha's, value proposition, support, etc.. would be of interest.  

Also, are there any alternative projects that are also worth
consideration?

Thanks,
Josh
