Yeah, Lifestreams isn't going to help with that - it's been made as a simpler mixed action stream which takes up much less space than jrAction, more of a site widget than a full listing page feature.
1. Create a lifestream on an admin or site profile, and use the profile_id parameter.
or
2. write a json array and pass that in as the services parameter.
It won't show jrActions from the entire site though, just that profile. I am testing code which shows sitewide actions/activity as well, so it should be in a future update.
iLoveHouseMusic:@Brian - I hate to spill the beans on this - and others may hate me.... but you can add the "profile_influences" field in the global config - therefore emulating the "Find New Artists" behavior....therefore bypassing the $9.
cheap, but as a vegetarian, beans are always interesting
