That may be true for the client running DNEWS - what's the overhead like
for the server it's sucking articles from?

I've seen some clients that sucked 8-) that implemented this by doing
some *horrible* things to the server - like "newnews * yymmdd hhmmss *"
which caused the 100MB history file to be read sequentially each time
they issued the command.
There are also some clients that do better, doing "group foo; xhdr
Message-ID" when they look for items in a specific group.
You would be doing your customers as well as their service providers
a favor if you detailed the server-side performance tradeoffs in your
future announcements.
