Yup, in the future I think any group regardless of whether you took part in the kill or not should be able to share credits with other ships in the group as long as all have the setting to share credits/bounties enabled. My Brother and I sometimes hang at nav points and while we gang up on larger vessels (and currently tag team the kills for credits) we tend to split up and get dragged apart chasing smaller prey... we want to consider ourselves a bounty collection team so sharing all income while grouped is what we want to be able to do.
