Other than the logistics of having one game talk to the other. I think it would be an interesting idea to create an NPC in oldschool that would be able to sell u the benefits of a bond for a certain amount of gp in old school. This can potentially be done by taking the bonds that are currently on the grand exchange and removing them when someone one when someone on oldschool buys the membership. Jagex would just need to keep a tab of how many bonds are available at any given time and should there be no bonds available on the grand exchange at that given moment the NPC can just say they ran out of stock or something try back later. This way Jagex still gets the money from the bond, the player on RS3 still gets his or her gp and the player in old school would get their membership without devaluing anything they worked for. The only issue I can see is that there needs to be a way to create a sink in RS3 to compensate which is no small matter. I am still thinking of a good way to increase of gold into rs3. Ill post again when i think of something or perhaps maybe someone else might have an idea that I am overlooking.
