well, you knew just what to search. i have spent more than one hour searching 
for "sco" and "sco csr" on the sf.net archives (which, as you surely know, 
are not very fast, have thousands of messages and have a shameful uptime) 
without finding anything useful. if you had kindly told me "look for 
something like scotest" or "look for a message from steven singer" i could 
have find the mail you were referring to in a minute.
