What does an Orca pilot get out of fleeting up?

I read this post on corp taxes and thought: " wouldn’t it be nice if a boosting pilot (of any kind) could simply charge for every boost he or she gives?" It would give and extra dimension to boosting and would make it lots easier and transparant what a boosting pilot is getting out of it.

Before implementing it would need careful deliberation on who is charging, who is paying and who is setting the charge. (FC/Boss/WC/boosting pilot/ pilot) That’s easy in a mining fleet, but not so easy in a pve fleet, difficult in PVP fleets and what about corp or alliance CTA’s?
