I get the impression from your other “Wave replacement” posts (which I’ve enjoyed a lot) that you try out these setups for a week or 2. I’m guessing the “free trial” of the business version would probably give you enough of a taste.
As you’ve noted before, it’s hard to find “everything” bundled in one place and even Wave didn’t solve that. While box.net wouldn’t be free if it was used to replace Wave (I consider the Google Apps integration to be critical) it might be better than the “roll your own” method you tried. ;-)
