Nice idea; I hadn't thought of it that way.  

When two articles with the same Message-ID appear, the second of these
are ignored, which is what we want.  So, yes, one could use an
nnvirtual group to "soft-switch" from one server to another for a
group.

The problem is that we want to do this with, say, 100 groups, and
nnvirtual is slow.  But something along those lines would do the
trick.

Some server support the "XPAT" (no, wait, it's called something else)
which allows you to say "XPAT MESSAGE-ID 1-1000".  Or something like
that.  It's very fast when dealing with headers that are in the
.overview files.
