You can set the INNCONF environment variable to a pathname of an alternate
inn.conf.  For example, you could create an alternate inn.conf that
was a copy of the real one, but with pathoverview set differently.
(If using buffindexed, also set pathetc to a different dir that has the
alternate buffindexed.conf; and link in the other pathetc files).

Then make a little script called, say, 'altoverchan':

export INNCONF
exec /path/to/overchan "$@"

And put 'altoverchan' in newsfeeds in place of 'overchan'.

Overchan uses the same overview API that innd uses, so you can use
any of the overview methods with it.
