Given the Usenet propagation delays, this might mean that it could take
up to a few days to receive a requested article.  This would make this
system unworkable for interactive browsing.  You might need to add a
separate server daemon to respond immediately to requests for articles.
You would also need to provide some mechanism for broadcasting or
multicasting the requests which does not waste too much bandwidth.
