I have 3 options for you: Airstash which let's you use any SD card and broadcasts using an ad-hoc wi-fi connection. I believe it is now under the Maxell brand -- it was independent when i got it. Kingston Wi-Drive works the same way, but has fixed memory (no SD or USB) -- comes in 16 or 32 Gb. I just to the 32 Gb for < $90. The third is the CloudFTP sold by Hypershop. This broadcasts an ad-hoc wi-Fi connection or it can join an existing wireless network. This device has a powered USB slot so you can you a USB stick, portable hard drive, or memory card reader. I have all 3 - Wi-Drive is nice as it is the size of an iPhone, but is not expandable. Airstash is ok, but seems too slow for video streaming sometimes. CloudFTP rocks! This started as a Kickstarter project by a college engineering student. Expandable with any USB Drive. I will now travel with that and a 500Gb hard drive for lots of videos! Both CloudFTP and WiDrive have no trouble streaming 1080p video!
