I propose the following protocol.
1) 'rnews -X ucbvax.1500 chico' will send the article ucbvax.1500
    to chico.
2) 'rnews -Y chico' lets news know that the article whos header
    is on standard input is available from chico.

    When an article is rec'd, all systems are either sent the
article as is done now, or a '-Y' uux request is sent if the
system accepts such (this fact will be noted in the .sys file)
and the article is bigger than a certain size (either wired in or
also in the .sys file).
    When a system receives a -Y request, it decides if it wants
the article.  If it does, then it creates a file in the news
directory which is empty, and returns a -X request.  When the
article comes in, it is put into the file.
    This protocol requires that three uux requests succeed.
This could be cut down but putting enough information in the
empty file to identify where the item is supposed to come from,
and periodically running around and finding all such empty files
that haven't been touched in a while, touching them, and
generating a new '-X' request.

    I have already implemented the '-X' code.
