At that point, why waste time with the pigeons? You have to meet anyway, just make it a data exchange instead and skip the pigeons completely. That also eliminates risk of packet loss with pigeons never arriving.
In a world with safe P2P via VPN and I2P, why would you use a pigeon? Then you never have to leave your house...or perhaps more importantly, you won't need to feed potentially hundreds of carrier pigeons and clean their cages.
