Hi Matt;

Drat!  Sorry about that.  I also re-ran some more tests and found that yes, 
the 3.1.13 web100clt process does not work with the 3.1.4 based 
server.  Sorry for the misleading statements.

Can you try looking at the 3.1.4b version again.  Run it against one of the 
Abilene based servers (ndt-newyork.abliene.ucaid.edu or one of the other 
servers listed on the http://e2epi.internet2.edu/ndt/ndt-server-list.html 
web page.  I can look at these servers to debug problems (I don't have 
access to the miranda server any more).
