shouldn't the OS' lookup routines handle whether the value from HOSTS or DNS is 
used automatically? i know that on some systems, one can specify to use HOSTS 
first (ie: USE_HOSTS_FIRST=1 [OS2] or /etc/host.conf [*nix])... i've seen it in 
winwhatever once upon a long time ago...

or am i misunderstanding this aspect and the apps used to perform DNS lookups 
are reacting to this setting and using one value or the other depending on the 
results returned from the initial query?
