So I can get both of these cache plugins to work by hooking into a few actions in bbPress and invalidating the post (which may be a topic or forum) and any ancestors (which would be a topic / forum in the case of a reply) by doing the ‘edit_post’ action on each post. There are a couple of edge cases still to deal with (like subscribing to a topic that needs your user page invalidating) that I’ll have a look at this evening.

Only real thing I don’t have an answer to is the freshness count. If you view a forum and the last topic was posted 1 minute ago then you come back an hour later and refresh the page you’ll see the cached page stating that the last topic was posted 1 minute ago rather than an hour ago. I could go with the fixed date approach but it’s not as neat.
