W3 Total Cache (or other caching) configurations that play nice with BuddyPress?

What are good configuration settings to make W3 Total Cache (or any other caching plugin, for that matter) play nice with BuddyPress?

BuddyPress.org codex page directs us to this not-so-useful-thread:

http://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/configuring-w3-total-cache-with-buddypress/?topic_page=2&num=15

And here's a not-so-helpful blog article on this topic by someone:

http://bp-tricks.com/featured/the-perfect-cdn-setup-for-buddypress-using-maxcdn-and-w3-total-cache/

You'll notice that at the end of each of these comment threads, I've asked for help to no avail.

So I figured it was time to turn to my "Being a WPMU DEV member is like having your own WordPress development team" people.

HELP?! What are good configuration settings to make W3 Total Cache (or any other caching plugin, for that matter) play nice with BuddyPress?!
