I started using PQI's Air Card, which enable most of the SD-card compatible digital cameras to be Wi-Fi compatible, similar to Eye-Fi,
but more flexible as it is implemented as a microSDHC adapter, capable with up to class 10 speed class.
Using with my Fujifilm FinePix Real 3D W1, it enables more close to a real-time posting to SNS, but only for 2D images... as the genuine app does not recognize .mpo, unfortunately.
As the product supports HTTP (and FTP), if your Phereo app can support direct image retrieval from its hosting memory card and upload, it would be so great.
...By the way, I do not understand how the genuine app discover the IP address of the card in the infrastructure client mode,
but I am afraid that it would be by a combination of the MAC address and HTTP reply, and my card's vencor ID is B0:38:29 - Siliconware Precision Industries Co., Ltd.
