Wouldn't this be a fairly simple thing to set up? You have one page that has summary records and when you click on one summary record you get the detail record. Perhaps it should be moderated so entries get a look at a moderator before they get accepted (moderator gets an email, clicks a "yes" or "no" link). There'd also be an "add new" page, a "delete/modify" page, etc.
Seems to me that you could take something like the room-reservation system and turn it into this.
Or, as you say, it could be done even more simply. Even a static HTML page that someone (or a few people) would be responsible for would work--that person, or persons, would get email sent to mailto:acshosts@openacs.org (or some other alias) and could just add/modify/delete entries as appropriate. Even if it kept up in a fairly desultory fashion, it would be better than nothing.
