20M Cr. would be easily payable by a wing trade voucher (5% of the profit on the transaction) if the escorted CMDR sold 400M Cr. of mined commodities.
I still see trust as the biggest obstacle to overcome - as some players have gone out of their way to gain it only to betray it at the "optimal" time.
It wouldn't be a direct transfer of credits, it would be like just like taking a mission and receiving credits by clicking "complete mission".
The player could create the escort mission and deposit the credits they're willing to pay the same way you deposit cargo for a cargo mission, insuring that the player already has enough money to cover the cost, and once the escort mission is complete the player clicks "mission complete", allowing the escort player to then select "mission complete" and receive their payment just like any other mission.
First of all, what is this wing trade voucher you speak of?
If this can be done I'm heading to Borann and Irula right now to offer my services.
Betrayal is definitely the biggest hurdle to overcome which is why a ranking and review system would be necessary so players would know what kind of player they're requesting. If you betray and gank your client everyone would know about it and no longer request your services.
This is the same problem that iridium wing had imho.
If the gankee is hardened enough to not get killed, it doesn't really need the escort in the first place.
If not, then the only way is to preemptively clear supercruise instances of all possible threats.
We did that in Colonia some times, but it's quite impratical and the biggest hurdle is instancing.
If my protectee is somehow not instancing with me, but in instance B with a ganker, say good bye.
That's one of the reasons I see blocking as very bad for the game. Not to give me more targets, but because of the negative
impact it can have on instancing.
