not necessarily. It should be if you want a "simple" UI.. INN is not
concidered as simple, according to feedbacks we can have here.
Anyway, I think simple and powerful are not contradictory. A well
designed UI can do the job.

The number of files is not a problem. Netscape did the job "quite" well
with its FastTrack(?) product based on INN 1.4x, and with Collabra later
(I've never used these products in production but I think they filled
a niche at this time and IMO it's still the case).
At my previous jobs, we were using our own Web based interface (I was not
the author) to manage all our feeds (INN + Diablo).. all Oleane peers
(should) know the "delegate" part of this interface.. (some are here).
Well, all this to prove that it's "doable".
I've started a project (mis-)called WebNews in 1996 and at this time,
I've also said that INN conf files were far too complex to be GUIfied.
So, I've stopped WebNews to first work on a big restructuration (file by file).
The idea was to have all files similar to innfeed.conf.
I've made the work for incoming.conf (released) and newsfeeds.conf (avorted
because of a lack of time). Aidan made readers.conf (also block oriented
but with a different approach), then someone (Katsuhiro?) made storage.conf.
Unfortunatly, these 4 first files are each using a different parser and
a (sligtly) different syntax. If Russ idea can be achieved, this will
ease the conception of a management API and then of adm tools (cmd line,

I'm used to work with +300 virtuals (Apache) in the same file, plus a Web
based admin tool (home made too) so once again, the size is not a problem.

control.ctl can also be GUIfied. It's quite similar to what has been done
with mailcap+mime.types converted in various application helpers.

I'm not particularly a GUI fan (I'm using mutt, slrn, vi and I'm happy with
them) but when you have to delegate the administration of a server, having
a GUI is not a luxury.
