I posted a photo of Andris Biedrins of the Golden State Warriors blocking a shot on my Instagram page just moments after it happened using this workflow with an OM-D, FlashAir card, and an iPad mini
I captured the original image (shown here) with an Olympus OM-D and a Zeiss 85mm lens. I had a Toshiba FlashAir SD card in the Olympus that fed the images to my iPad mini. From the iPad, I uploaded the photo to Instagram.
The image looks fine on my iPhone 4S, but it isn't a top quality rendering. That's why I capture in RAW+JPEG for this workflow. The JPEG goes to Instagram, then I process the RAW file in Aperture 3.4 when I get home. That's the image I've posted here.
I like being able to share images in real time, yet still have top quality files for printing and publishing. I'll continue making adjustments to this system, but thought you might find it interesting.
