First of all, my apologies for not having answered sooner. I am aware
your original message dates back to three years ago! Better answering
now than never, though.

Couldn't you run innfeed in funnel-file mode instead of channel mode?
This way, innd would continually write to a file that would continually
be processed by innfeed.

Maybe the funnel-file mode I am speaking about is what you are hinting
at here. Instead of editing innfeed to tail the funnel-file on its own,
a separate script doing that could be periodically run by crond.

Would you mind if we mention innduct in:
* the "Related Packages" section of README
* the innfeed man page (maybe in the "BUGS" section, as a workaround to
the lossy behaviour you mention, or in a new "ALTERNATIVE" section)
Other INN-related pages you see on which it would be worth mentioning
innduct? (maybe nntpsend and innxmit)
Is the URL
OK for you to use, or do you prefer another one? (tarball, HTML page
describing the project or HTML version of the man page...)
Thanks again for your work, and sorry for only getting back to you now...
