I assume you mean the issues you raised about RSS requirements. You wrote:

note that RSS requires title, link, description, etc. because they're core to syndication

First, RSS doesn't require description. Second, it's easy to automatically generate a title based on other things (time, participants, or just plain "Untitled") as well as *some* sort of link, for those feeds for which this doesn't make sense. I think the benefits of using the RSS format outweigh these costs.
