If you grab the ntd source from http://e2epi.internet2.edu/ndt/
there is the web100clt command-line client in there that will do the 
same tests as the Java applet. Combine that with your favorite scripting 
language and  your favorite database and you should be good to go. As 
you mentioned it would be best to use large multi-day/week random delays 
between sampling - if everyone ran something like that they would need 
to shut the servers down.  It also might be more interesting to sample a 
few times during a 24-hour period, then wait 8-17 days and try again to 
build up a feel if any bandwidth issues are time of day or day of week 
based.
